Jennifer Lopez goes from white onesie to business casual look for NYC return after celebrating 55th birthday without Ben Affleck

After celebrating her birthday, Jennifer Lopez effortlessly transitions from a beachy look to a chic city look.

The 55-year-old Golden Globe nominee arrived back in New York City on Thursday after celebrating her 55th birthday in the Hamptons without husband Ben Affleck.

She looked comfortable as she stepped off the tour bus in an off-white sleeveless onesie and checked into her hotel.

Lopez paired the ensemble with a matching, soft, ankle-length cardigan with long, wide sleeves.

Shortly after, she headed for an early lunch at Balthazar in SoHo, where she served up yet another stylish, white summer look.

Lopez showed off her toned stomach in a white crop top, worn under a matching jacket with cutouts in the sleeves.

The Hustlers actress paired the look with drawstring jeans and chunky, open-toe cork heels.

She completed the look with gold sunglasses and earrings, this time with a black Birkin.

Lopez previously celebrated her 55th birthday with a Bridgerton-themed party, which Affleck, 51, did not attend.

The Jenny from the Block artist thanked her fans for their birthday wishes in a post. “I honestly have the best, most amazing fans in the world,” she wrote.

“I can never express how touched I am or how incredibly blessed I feel to have you all in my life. Thank you so much,” Lopez continued.

“It’s hard to believe we’ve spent all this time together,” she added. “It’s funny how, as I sit here and reflect on the most extraordinary journey, I still feel like I’m the same girl who was so full of energy and bravado at the beginning, so ready to take on the world on the outside and yet so tender, vulnerable and sometimes afraid, but always full of love on the inside.

Lopez and Affleck previously celebrated their second wedding anniversary separately, after putting their Beverly Hills home on the market for $68 million earlier this month.

Reports of the couple’s marital problems surfaced in May, after they had not been seen together since late March.

A source told In Touch at the time, “Ben has already moved out and they will likely have to sell the dream home they’ve been looking for for two years.

“They will never stop loving each other, but she can’t control him and he can’t change her. There’s no way it could have lasted.”

One of Jennifer’s friends from LA told the Daily Mail: ‘If it’s just a matter of putting in the effort, then you better trust that [Jen] will turn it around.

“She’s put her heart and soul into her love story with Ben and she’s not going to give it up without a fight,” the source added. “From what I hear there’s still a lot of love, so there has to be hope.”
