"Britney got to the show right before it started," an eyewitness tells Star. "As soon as the music for the show started, she was bopping her head to the beat, and chewing gum with her mouth wide open."

"She seemed to be having a really good time, giggling with her girlfriend and discussing which outfits looked good. When a model walked out in a green, floral print dress, she seemed to like it a lot, clapping very enthusiastically."

"There were a few moments when she seemed to get bored and would bite her nails, then stare at them to make sure they were even!"

After the show, Spears told PEOPLE of the collection: "It was amazing."

Kimora Lee Simmons, who was backstage after the show, said of Spears: "Sometimes she gets a hard rap...[But] she is a very talented girl."

In other news, Britney Spears says it's "awesome" being single.
The 'Toxic' singer filed for divorce from estranged husband Kevin Federline
last November and insists she is enjoying being on her own.
Speaking at a New York fashion show last week, she said: "It's awesome! I'm
loving it."
Since splitting from Kevin, Britney - who has two sons, 16-month-old Sean
Preston and four-month-old Jayden James, with the budding rapper - has been
romantically linked to model Isaac Cohen and has been a regular on the Los
Angeles and Las Vegas party scenes.
In the immediate aftermath of the separation, the pop superstar was seen out
on several occasions with Paris Hilton but their friendship has now cooled.
