If you're one of the few that can stomach daily updates on Britney Spears, you'll notice that many video clips and photos show her packing around a cup of Starbucks coffee -- in many cases, a grande frappuccino with whipped cream.

"Maybe (all those frappuccinos) explain why the so-called princess of pop has put on so many pounds lately," cracks the Starbucks Gossip blog.
