• Rumer Willis stayed under the radar at the T-Mobile and Google Music-sponsored party at a private residence in the West Hollywood Hills. The starlet, who was recently in Europe, arrived at the bash (for Redlight Management) with two friends, but spent most of the night hanging out with Glee's Mark Sallling, who arrived earlier via taxi. The two chatted with each other all night, and their interactions seemed friendly, not romantic, says an observer, who noted that the two did leave the party together.
