While Britney Spears’ behavior continues to get more erratic she has the support of one celeb: Paris Hilton.

Usmagazine.com caught up with the heiress, 26, over the weekend at the Sundance Film Festival, where she was promoting her new gross-out comedy The Hottie and the Nottie (out February 8).

“She’s such a sweet girl when I’m alone with her, she’s a completely different person than she’s made out to be,” Hilton told. “And I love her, I think she’s very sweet and has a big heart. She’s amazing.”

Hilton’s well-wishes for the troubled pop star?

“I just want her to be happy,” she said. “I think everything’s going to be OK.”
