Super tan Christina Aguilera took her mom out for a very public Mother's Day at The Ivy yesterday. Her mom looks like she was enjoying a little bit of celebrity glamor for her special day. The timing was perfect with Christina's tour in California for the weekend. She has one more show in San Diego on the 21st before leaving for her World Tour which kicks off in Japan on June 18th. Hopefully mom can make it to some of those dates as well!
