It's Amanda Bynes! She tells Rachael that during the filming of Hairspray, she got to fulfill a dream of many Grease fans -- to sing "Summer Lovin'" with her co-star John Travolta! "Tell me more, tell me more …"

While working on her new movie Sydney White, Amanda hit a big milestone -- her 21st birthday! She and Rachael discuss their similar experiences reaching the legal drinking age, and that when they finally had proof they could buy alcohol, no one asked for it!

An accomplished actress and singer, Amanda has also designed a line of clothing for Steve & Barry's stores. It’s called Dear and every item in her line is under $20! Rachael asks Amanda who she looks up to for style. "Sarah Jessica Parker," says Amanda, "I think she always does a good job. She mixes it up and picks stuff that fits her personality."
