Paulina Gretzky Returns To Instagram With Sexy Bikini Photo

Paulina Gretzky's back, and just as sexy as ever! Well, sort of...

The 25-year-old posted a steamy snap on Instagram this morning (Nov. 14) of herself, along with two friends, posing on a boat. Naturally, the blond-haired beauty is clad in a bikini and aviator shades. In the caption, she wished her friend Sarah a Happy Birthday.

Happy Birthday Beautiful @sara.cuse!! Love you 💃✨🎂❤️

Judging from her flat tummy in the pic, we're assuming the shot is a flashback to her pre-baby bump days (the Great One's daughter is expecting her first child with fiance Dustin Johnson).

While she's known for her sexy selfies, the Los Angeles-born celebutante has been keeping things pretty low key lately (especially since news of Johnson's drug use first surfaced).

Last month, she showed off her growing baby belly, and shared a no-makeup selfie via Instagram.

It's good to have her back online (even for only a day)!

Just a few of her sexiest moments:
