Britney Spears showed some support for her ex-boyfriend Justin Timberlake while on vacation Wednesday – three weeks after he announced his Lyme disease diagnosis.

The 43-year-old Grammy winner stripped down to a green-and-yellow string bikini while dancing aboard a boat to Manon Dave’s remix of Timbaland’s song Carry Out featuring the 44-year-old pop star.

The glitchy hip-hop track reached No. 11 on the US Billboard Hot 100 back in 2009.

Britney and Justin – who dated between 2000-2003 – originally met as children starring as Mouseketeers on The Disney Channel’s The Mickey Mouse Club from 1993-1994.

In Spears’ 2023 memoir The Woman In Me, she revealed that Timberlake urged her to have an abortion when they unexpectedly became pregnant.

‘It was a surprise, but for me, it wasn’t a tragedy. I loved Justin so much. I always expected us to have a family together one day. This would just be much earlier than I’d anticipated,’ the semi-retired pop star wrote.

‘But Justin definitely wasn’t happy about the pregnancy. He said we weren’t ready to have a baby in our lives, that we were way too young. If it had been left up to me alone, I never would have done it. And yet Justin was so sure that he didn’t want to be a father. To this day, [the abortion was] one of the most agonizing things I have ever experienced in my life.’

The 10-time Grammy winner received substantial backlash online about his low-effort performances on his Forget Tomorrow World Tour, and he pled guilty to driving while impaired on September 13 stemming from his 2024 arrest.

In the same Instagram video, Britney introduced her 157.2M social media following to ‘the realest man out here in this water’ while affecting a British accent.

‘We went snorkeling all day yesterday in water,’ Spears, looking a tad sunburned, continued.

‘This is like, um, Turks and Caicos [Islands]!’

The Hold Me Closer hitmaker posted a second video of herself on the shoreline beside a mystery man and she’s heard saying, ‘Guys look, it gonna bite me!’ before cheerfully thanking someone off camera.

Britney was wearing a pink Joanne-style boater hat and she drew attention to her floral choker, which is a piece from her upcoming jewelry brand, B. Tiny.

On Monday, Spears sparked concern by posting a video of herself fiddling with the usually off-camera ring light and bizarrely vocalizing in the messy living room of her $10M Thousand Oaks mansion.

‘I would say, Julia Roberts singing Prince’s Kiss off key a touch, but I sounded really good behind the lens LOL!’ the Mississippi-born singer defended hours later.

‘PSS Wise a**es, I do know who I am! I have eight different languages written on my neck. These are my PJs, but I put these boots on to play with lighting – not the most elegant look, but hey!’

Last November, Britney made her final $20K child support payment ($5M total) to her 47-year-old former back-up dancer, whom she was only married to for two years before their 2007 divorce (pictured in 2004)

Britney is said to be hands on with her fully-authorized biopic for Universal Pictures, which will be helmed by Wicked director Jon M. Chu.

Spears’ second ex-husband Kevin Federline recently announced that Listenin will publish his 228-page memoir You Thought You Knew – co-written by Alex Holstein and Jaren Hayman – on October 21, which is about being a ‘devoted father fighting for his children.’

The former Mouseketeer’s third ex-husband Sam Asghari joked to TMZ last Friday: ‘Well, he was a professional father so he would be a great… it would be the first book that’ll tell you how to be a professional father.’

Last November, Britney made her final $20K child support payment to her 47-year-old former back-up dancer, whom she was only married to for two years before their 2007 divorce.

Kevin amassed $5M in support payments during the 17 years he had primary custody of their sons Jayden and Sean, who celebrate their 19th and 20th birthdays next month.

Federline has claimed he was ‘not involved’ in Spears’ 13-year conservatorship (which ended in 2021) despite her former manager Larry Rudolph reportedly describing him as a ‘necessary party’ to the 2008 intervention after her meltdown over their custody arrangement.

Most conservatees are deemed ‘gravely disabled’ by the court and unable to meet their basic needs of food, clothing, and shelter – while Britney was put to work recording four studio albums, a judging gig on The X Factor, and a grueling two-year Las Vegas residency.
