Britney Spears does scantily-clad dance in her garage gym... after blasting ex Kevin Federline

On Tuesday, Grammy winner Britney Spears shared yet another scantily-clad video of her dancing by herself and 'messing around in the garage gym' of her new $11.8M six-bedroom Calabasas mansion.

The 40-year-old newlywed - who boasts 155.3M social media followers - posted a 45-second video of herself showing off her moves to N.E.R.D's 2004 song She Wants To Move.

Britney loves reposting footage of herself and this clip was no different having been technically shot last Friday when she declared: 'I'm proud I lost 5 pounds.'

In one shot, Spears' husband of two months - Hot Seat actor Sam Asghari - could be seen in the reflection of the mirror dutifully filming her dancing on his phone.

The Mississippi-born beauty's video also included two-month-old footage of her posing in a black pantsuit with a plunging corset bodice and brown platform pumps.

Britney's signature fringed blonde locks appeared to be freshly coiffed in large waves for the clip.

Spears' Instagram post came after she blasted her ex-husband #2 Kevin Federline for doing a 'hurtful' interview with ITV News all about her, their marriage, and their children.

'The boys have decided they are not seeing her right now,' the 44-year-old former backup dancer claimed.

'It's been a few months since they've seen her. They made the decision not to go to her [June 9] wedding.'

Kevin indicated that their sons - Sean Preston, 16; and Jayden James, 15 - are embarrassed by the former Mouseketeer's frequent posts of herself nearly nude.

'I try to explain to them, "Look, maybe that's just another way she tries to express herself,"' Federline - who's said to receive $20K/month in child support - explained.

'But that doesn't take away from the fact of what it does to them. It's tough. I can't imagine how it feels to be a teenager having to go to high school.'

In 2019, the Cali-born, Nevada-raised reality star was granted 70% custody of their sons while Britney was downgraded to 30% - according to TMZ. 

Kevin also defended Britney's estranged father - former building contractor Jamie Spears - who controlled every aspect of her life during a 13-year conservatorship, which ended on November 12.

'100% I feel like he saved her back then,' Federline gushed.

'I saw a man that really cared, and wanting everything to be okay...I would absolutely welcome Jamie Spears back in the boys' lives.'

The PopoZão rapper's two-year marriage to Spears ended in July 2007, and just six months later she was put on 5150 involuntary psychiatric hold.

On Saturday night, the Matches singer said it 'saddened' her to hear Kevin speaking so publicly about private family matters.

Any day now, Britney is set to make her triumphant return to music thanks to a recently-recorded duet with legendary pop star Elton John.
