For some stars, there's only one way to celebrate Independence Day: by donning skimpy, flag-inspired bikinis.

Kathy Griffin, 51, Heidi Montag, 25, and Lisa Rinna, 48, are just three celebs who have showed off their American pride in red, white and blue two-pieces.

"It's frustration and starvation," comedienne Griffin has joked of her bikini body. "I'm cranky all the time and I'm hungry all the time."

As for Montag? "I've been running a lot, and I've been doing weights," The Hills alum told Us Weekly in 2011. "When you work out, you boost your metabolism, so you have to [make sure you eat enough]."
