Diane Kruger is proving the adage that age is really just a number with her latest sizzling bikini shot. The Inglourious Basterds actress, who turns 40 on Friday, took to Instagram Sunday to show off her incredible abs and toned body, and it's clear she's still got it.
"Sunday Fun Day :)," the fresh-faced model captioned the black-and-white shot, which shows off her entire toned torso in a black bikini top. In the photo, the blond stunner has her arms outstretched towards the sky as she stands in an infinity pool.
This isn't the first time Kruger's put her toned abes on display. The fashion-forward star stepped out in April in a striped crop top and A-line miniskirt, proving she's always game to take on the hottest trends—or a sexy (often self-deprecating) selfie, like these recent ones below.
No word yet on the birthday girl's plans, but something tells us she'll be spending the milestone day with longtime boyfriend and The Affair star Joshua Jackson, whom she moved in with after 10 years of dating this past March.
