Everything you want to know about this rising star.

With her blonde hair and genuine vibe, Blake Lively is the one to root for on The CW's "Gossip Girl." Now, we've got all the vital stats on this "It Girl"!

"I'm just in this fantasy world right now, I don't even feel like I'm living it," she tells us.

At 20 years old, Blake grew up in a family of actors. Her mom, dad and four siblings (two brothers and two sisters) were all in the business, but this rebel preferred the academic life. 

"I'm so involved in school," she told us of back then. "I'm in every activity there is to be involved in. Every difficult class I can take, I'm taking it."

The 5-foot, 10-inch tall star was also a cheerleader and class president, and gushed that she couldn't wait to go to her prom!

At a fluke audition suggested by her brother, she landed her first substantial role as Bridget in 2005's 'Sisterhood of the Traveling Pants.' And her real-life dad, Ernie, played her pop in the sequel, in theaters now.

"I never wanted to act," she confesses. "I grew up watching him and going to his auditions and coaching him."

Now she's landed the cushy role of Serena Van Der Woodsen, which returns with new shows on Sept. 1, and has just earned Teen Choice Awards for Choice TV Breakout Star (Female) and Choice TV Actress (Drama). But the best part? She got to walk the carpet with her hunky co-star and rumored boyfriend, Penn Badgley!
