The 37-year-old actress showed her Independence Day (04.07.16) joy by sharing with her 4.7 million followers a photo of herself modelling her new Fabletics American flag-themed sportswear that showed off her perfectly toned body, which she joked was photoshopped.

Alongside the picture, she wrote: "From my airbrushed ass to yours ... Happy fourth!!! (sic)"

The 'Bride Wars' star seems to be in the mood for sharing sexy photos as just a few days ago she surprised her fans with a naked picture on Instagram.

Alongside the pic, in which she could be seen posing with her back to the camera in dull lighting with one hand on her hip and the other in the air, she wrote: "#tbt #PrettyHappy #LOVE #AlmostFriday cred @darren_ankenman (sic)"

The 'Almost Famous' star - who is the daughter of Hollywood veteran Goldie Hawn and Bill Hudson - says she was taught how to embrace her body by her mother.

She said: "My mom always celebrated the female body so she gave me confidence. I felt that when I started becoming a woman and getting my figure, it was celebrated."

And she's previously admitted she prefers being naked because her family has always been comfortable with baring all.

She said: "My family's always been a comfortably naked family, I'd much prefer being naked than clothed, I just find clothes restricting. When I get home I just want to be naked.

"When you're a dancer, you're very comfortable with your body...and my mom was a dancer."
