Simon Cowell's baby mama-to-be Lauren Silverman was the belle of the ball at her baby shower in Beverly Hills Sunday, Breaking Celebrity News has learned.

The 54-year-old music mogul was at the Peninsula Hotel during the festivities, E! reported, while many of his ex-lovers -- including Mezhgan Hussainy and Terri Seymour -- were there to celebrate with Silverman.

More details from the celebration: It was decked out in blue and white (as the couple is expecting a boy); a muscle-bound male server gave out drinks; and a stunning floral arrangement was composed using white orchids, yellow orchids, blue hydrangeas and white roses.
