Christina Aguilera: SLS SLS SLS!

Christina Aguilera hops out of her car and walks into the SLS Hotel after attending a meeting on Tuesday (October 26) in Beverly Hills, Calif.

Over the weekend, the 29-year-old newly single singer lent her talent to pal Justin Timberlake‘s benefit concert at Planet Hollywood in Las Vegas, Nevada.

After the concert, Christina took her backup dancers out for a night of fun at Tao, where they partied together until 3am.

FYI: Christina is carrying Christian Louboutin‘s Marianna Rider handbag.
