Jennifer Lopez is showing off her toned figure as she celebrates her milestone 55th birthday with husband Ben Affleck nowhere in sight

Lopez appeared unfazed by the divorce rumors as she posed in a plunging white one-piece swimsuit for a sexy new mirror selfie she shared on Instagram Wednesday.

The pop diva paired the swimsuit with gold jewelry, including hoop earrings, bangles and a large ring.

One piece that was noticeably absent from Lopez's fingers was her wedding ring.

"This Is Me...Now [birthday cake emoji]," she captioned the photo.

According to TMZ, Lopez was still rocking her wedding band when she stepped out in the Hamptons in New York Monday.

Affleck, who remains in Los Angeles despite his wife celebrating her birthday this week, was also seen without his wedding ring Sunday.

Rumors have swirled for months that Lopez and Affleck's marriage is on the rocks and that they are headed for a divorce just two years after tying the knot in Las Vegas.

In May, Affleck moved out of their Beverly Hills marital home, which they've since listed for sale. He was also absent from the premiere and promo of Lopez's latest film, "Atlas."

The couple also hasn't been photographed together in a month, with Affleck skipping her "Bridgerton"-inspired birthday bash Saturday.

An unnamed source recently told Fox News Digital that the Oscar winner and the singer-actress are "not getting back together" and "not trying to work it out."

However, more recently, the Daily Mail reported that Lopez and Affleck have decided to give their marriage one more chance and are now working to rekindle their romance.

An unnamed insider told the outlet that the two stars were "ready to throw in the towel" and their "divorce papers are done and ready to be filed."

However, the source claimed that Lopez and Affleck "wanted to give it one last go before walking away from this."

The "On the Floor" singer and "Justice League" star "are going back to the beginning by writing each other letters. This is what made them fall in love in the first place," the insider added.
