Victoria Beckham has some serious willpower!

The super-slim star, who turned 38 Tuesday, posted a picture of her celebratory birthday dessert -- fruit!

"Birthday lunch!!! Such a lovely day!!!! X vb," she tweeted Tuesday along with a photo of a summer fruit plate filled with mango, pineapple, oranges, an assortment of berries and "Happy Birthday Victoria" scripted around the plate's edges in chocolate syrup.

Her healthy dessert comes as no surprise. Going by the slim star's reported eating habits, sugary sweets aren't in order even on her special days.

While dining at Il Pastaio in Beverly Hills last month, an onlooker has told Us Weekly about the star's recent eating habits. "All I saw her eat was arugula -- not even any salad dressing!"

But even though she didn't indulge in a piece of buttercream frosted cake, Victoria was properly feted with several birthday festivities.

Her husband of 12 years, David Beckham, and their four children, sons Brooklyn, 12, Romeo, 9, Cruz, 7, and daughter Harper, 8 months, decked out their home with purple and white balloons and four bouquets of roses (presumably one from each family member) and a banner that reads "Happy Birthday Mummy!"

Not to mention, she even received celebratory flowers from her star BFF Eva Longoria.

"Thank you Eva Longoria for such beautiful flowers!!! super chic! X vb" she tweeted.
