Fergie Vacation in Mexico,Looking good, Fergie!

We've seen our fair share of celebrity bikini photos recently, but this one may take the cake. Fergie spent her holiday weekend soaking up the sun in Mexico and tweeted a photo of herself -- complete with her rock-hard abs -- posing in a sexy bikini. If this isn't motivation to get in beach shape, we don't know what is!

The photo may also put to rest any lingering pregnancy rumors that seem to constantly follow the star, who is married to actor Josh Duhamel.

Earlier in the day, the Black Eyed Peas singer tweeted about her gratitude for all those serving in the U.S. military, writing, "Thank you to all the beautiful brave souls this Memorial Day."
