LOS ANGELES, CA  [Tuesday Jun.5.2007]  /WMQT.com/ -- You know what they say...the couple that plays together, stays together.

Hopefully this is the case for pop princess Ashlee Simpson, who brought some sizzle into the studio when she recorded a track with her current flame, Fall Out Boy's Pete Wentz.

According to punkbands.com, the collaboration is set to appear on Ashlee's upcoming album, which is due out later this year.
