Gisele Bundchen highlights her svelte figure in athletic outfit for a dog walk in Miami… after ex Tom Brad posted cryptic quote about a ‘lying cheating heart’ over a year after their split

Gisele Bündchen looked toned and fit on Friday as she got some fresh air with one of her dogs.

The 43-year-old supermodel was spotted taking a walk in Miami with her huge black and tan German Shepherd following on a leash by her side.

The catwalk star was dressed in a simple athleisure ensemble that showed off her lithe figure and her long legs.

The outing comes just days after her ex-husband Tom Brady shared a cryptic quote from Muhammad Ali referring to a “lying, deceiving heart.”

The post, which had no additional context, appeared just over a year after he and Gisele ended their marriage.

Gisele's dog-walking look consisted of a flowing gray long-sleeved shirt that hung loosely on her slim body.

She contrasted it with a set of short midnight blue leggings, and with a set of white sneakers she looked ready for anything.

Her dirty blonde hair was messily tied and pressed under a weathered gray baseball cap.

The model also wore a black sports bra and had a set of Apple AirPods wedged into her ears for some outdoor entertainment.

Gisele's German Shepherd's name doesn't appear to have been previously mentioned, and the dog is apparently the newest of her pups, as he was first pictured with her earlier this year.

She has also had several older dogs that she shared with her ex-husband, a football star.

The retired NFL star, 46 – who is currently courting supermodel Irina Shayk – uploaded the lengthy quote from legendary boxer Muhammad Ali to his Instagram Stories on Tuesday.

In it, the late athlete explains that the “heart,” whether good or bad, guides us, and that only someone with a true, loving heart can be “great.”

It also warns that those who lack morality, kindness and love will never truly achieve greatness, regardless of their worldly achievements.

Brady's Insta Stories post comes months after Gisele admitted that she was “just surviving” during their 13-year marriage and that they simply “grew apart.”

It also comes amid rumors – which Gisele has vehemently denied – that she has moved on with her jiu-jitsu instructor Joaquim Valente following their split in October 2022.

Earlier this year she said Vanity fair that the media is simply trying to 'tie' her to someone now that she is a single woman.

Gisele also expressed her gratitude to her “great friend” Valente for helping her and her children navigate this new chapter of their lives.

'The personality of a person. The manners of a person. His thoughts. His actions. his actions,” Ali's quote begins. 'It's all based on his heart.

'For what is a human being? A man is his heart. A lying, deceitful heart means a lying, deceitful man. A loving, merciful heart means a loving, merciful man.”

Ali also talks about the true meaning of “life,” as he explains that “a living heart” is that of a “living man,” while a “dead heart” is a “dead man.”

He further emphasizes that a man's greatness is not determined by his status, but rather by his character.

'Regardless of a man's title. No matter a man's rank, wealth or position, if the heart is not great, he cannot be great.

“But if the heart is big, a man remains big in all circumstances, rich or poor, big or small, because it is the heart that makes a person big or small,” the quote concludes.

Brady added his own two cents, encouraging his 14.6 million followers to “be proud of the man in the glass.”

Brady and Bündchen started dating in 2007 before tying the knot in 2009.

They were together for more than a decade and welcomed two children — 11-year-old daughter Vivian Lake and son Benjamin, 13 — before confirming their divorce in October 2022.

In separate statements, they said it took “much consideration” before they made the “difficult” and “painful” decision to end their marriage.

Gisele noted that they “finalized the divorce amicably,” while Brady said they “wished only the best for each other.”

She said CBS News Sunday morning that she has happily entered a new era of her life and finally feels like she is 'alive'.

Brady is seemingly back in the dating game, as he recently rekindled his romance with Irina Shayk, 37.

The Russian catwalk expert and the former footballer became the subject of dating rumors after reportedly dating in July.

Like Brady, Shayk is also older, as she shares a six-year-old daughter named Lea with ex Bradley Cooper, 48.

Months later, it was reported that their affair 'ended up', but reconnected this month after being spotted in each other's company in Miami, Florida.

Earlier this week, DailyMail.com exclusively revealed that Brady and Shayk could soon take the next step by making their romance 'official'.

Insiders indicated that the couple is comfortable with their connection becoming “permanent” — but no one wants to make the first move.

“Tom and Irina are dating again, but they don't have a real relationship,” the source said. 'They are attracted to each other and like to hang out, but play the game of hanging out when it suits them.

“They continue to talk and get comfortable with each other, where it will lead to something more lasting if they let it.

“It has all the elements that they are fighting against, someone just needs to take the step to make it official, but no one wants to be the first.

“When you're in a good relationship and you get to the love stage and you're thinking about when to say, 'I love you,' and no one wants to say it before the other person, then that's what happens with Tom and Irina.”

The source then noted, “They know what it could be, they're just fighting it, not in a negative way, they just don't want to hurt each other's feelings and are trying to pace themselves with each other.”

Tellingly, Tom stepped out solo last Thursday as he joined a host of A-listers for the launch of new luxury resort, Fountainebleau Las Vegas.

It came days after his apparent one-on-one meeting with Shayk after reuniting at Art Basel.
