Christina Aguilera was among the many stars who just arrived at The Grammy Nominations Concert Live!! bash held at the Nokia Theatre in Los Angeles on Wednesday.

On the red carpet, the 27-year-old new mom said she’s navigating the “balancing act” she expected when she took on parenthood with her hubby, Jordan Bratman. “I wasn’t going to give up who I was before I had the baby,” Xtina said. “It’s important to stay true to that as an example — also for my son to find out what his goals are, what he’s passionate about doing, so it’s sort of leading by example in that sense,” she said. “It’s a tough thing. I had a moment leaving him today to get ready for tonight of missing him, but every working mom goes through it. They know what it feels like.”

The one-hour primetime special, which will air live tonight on CBS, will announce nominations in several top categories, feature performances by past Grammy winners and nominees, and will set the stage for the 51st Annual Grammy Awards on February 8.

The show is hosted by the unusual pairing of two-time Grammy winner LL Cool J and Grammy nominee Taylor Swift. Performers include five-time Grammy winner Mariah Carey, five-time winner Celine Dion, six-time winner Foo Fighters, 14-time winner B.B. King and, of course, Xtina.

Five-time winner John Mayer is also slated to perform a one hour concert for the live audience after the television taping.

The special coincides with the grand opening of the Grammy Museum, and proceeds from the event benefit the Museum. Tickets to attend the live taping ranged from $50 to $500 while VIP Package seats were as high as $6000!!
