Amanda Holden shows off her flexibility in a white blazer dress

Amanda Holden paired sexy and chic in a low-back white blazer dress as she headed to work at Heart FM on Thursday.

The stunner, 51, showed off her incredible legs in the Karen Millen number, which was buttoned up in the front and featured a cut-out section in the back.

She paired the sexy number with a pair of white ombre heels and completed her ensemble with a matching handbag.

Amanda wore oversized sunglasses and a pretty necklace that complemented her golden tan.

The radio star took to Instagram shortly after to reveal that the team had woken up to incredible news.

She wrote, “11.3 million of you are listening with us every week on @thisisheart. Thank you for being part of our Heart Breakfast family.”

Showing off her outfit in a video on Stories, she said, “I really like the lapels you can tuck under here.

“There’s a cheeky little cutout in the back that’s gorgeous. I like the pocket details. It runs quite wide, so I think I’m going to get a size smaller.

“I just think it’s a really cool dress. I have a business appointment today, but I feel bold enough. It’s not too formal.

“I also think you could go to dinner or lunch or a wedding or a christening. Have a fantastic day.’

Then she showed her incredible flexibility by balancing her leg on a pole while standing by a window.

Amanda squealed in delight when her co-host Jamie Theakston was “naked” live on Tuesday morning.

The judges on Britain’s Got Talent were all smiles as she presented her radio show to Jamie, 52, who took his clothes off.

Amanda couldn’t contain her laughter as she quickly pulled out her phone to film her co-host as he flexed his muscles towards the camera.

She said, “Jamie Theakston, in fact I went live on my Instagram. If you want to see Jamie Theakston naked live on the radio’.

He added, “Only from the waist down,” but Amanda said she “couldn’t see what was under” the desk from where she was sitting.

Jamie joked that was “probably for the best” as he continued with the Breakfast Show announcements and what will be on tomorrow.

Amanda interrupted and yelled, “Are you getting dressed?”

As Jamie got up from the desk in the studio, Amanda added, “Oh yes!”

Jamie later revealed the reason why he was shirtless, saying, ‘Someone took my clothes. I don’t have a top, I was just trying on a T-shirt, now I have nothing to wear.’

Her fans took to Amanda’s Instagram post and rushed to the comments to joke that Jamie has become the “radio streaker.”
