That cute bejeweled heart necklace around Christina Aguilera's neck gives a shout out to her son Max. I can almost feel the love in her heart as she heads into her local Agent Provocateur to do a little lingerie shopping.

According to our sources:

Christina Aguilera flashes photographers a demure pouty smile as she leaves lunch at LaScala Restaurant and stops in at Agent Provocateur where she purchased an array of lingerie in Beverly Hills, CA today.

Is she secretly planning to make little Max a younger brother or sister with hubbie Jordan Bratman? I guess we'll have to wait and see.
