What's behind Jessica's new pout?

It seems that American pop singer Jessica Simpson has got a lip job done once again.

The 27-year-old singer recently showed off larger lips at LAX airport in L.A.

In the October 2006 issue of Glamour magazine, she confessed for the first time that she got lip injections.

"I had that Restylane stuff," Usmagazine.com quoted her, as telling the mag.

"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!" she added.

Simpson is reportedly dating Dallas Cowboy quarterback Tony Romo for some weeks now.
