Teaming up for a festive night on the town, the lovely ladies of the CW were out for a pre-upfront party in New York City on Wednesday night (May 20).

Joining in on the fun were the hotties from "90210," as AnnaLynne McCord, Shenae Grimes, Jessica Stroup and Jessica Lowndes all made separate arrivals.

Also in attendance was Ashlee Simpson, who is starring in the revamped version of "melrose Place" - set to kick off its first season this fall.

Recent rumors tell that the CW plans to drop "Melrose Place" behind "90210" on Tuesday nights as part of its schedule makeover for the 2009-10 season. The network will reportedly send "90210's" current follow-up, "Smallville," back to Friday nights - with all to be confirmed later today.
