Simpson Sisters' Airport Rendezvous

With rumors of a pregnancy swirling around her, Ashlee Simpson was spotted arriving at LAX airport on Monday sporting her shiny, new engagement ring.

The Pieces Of Me singer made her way into the travel hub just 10 minutes after big sister Jessica toted her pet pooch Daisy past security without a hitch.

As previously reported by Gossip Girls, an Us Weekly source claims that Ashlee and her Fall Out Boy bassist fiance Pete Wentz are not only getting married - but also expecting their first child together. However, neither of the star's reps have confirmed the story thus far.

And amidst all of the big news in her personal life, Ashlee is also readying for the release her new album, Bittersweet World, in stores on April 22nd.
