However, the Dukes of Hazzard star admits that her suddenly-puffier pout wasn't natural and that she hated the results.

Many gossip magazines had speculated last year that she might have pumped up her lips with collagen, as they looked awkwardly swollen.

Simpson now reveals that she did indeed artificially plump her lips up last year in autumn with the protein-based gel Restylane, which is reportedly safer than traditional collagen.

"I had that Restylane stuff. It looked fake to me. I didn't like that. But... it went away in, like, four months. My lips are back to what they were. Thank God!," Contactmusic quoted her as telling Glamour magazine.
