Xtina To Make First Appearance Since Birth of Baby Max!

Christina called in to Ryan Seacrest's radio show this morning, and the new mom (who gave birth almost a month ago) confessed that she's going "stir crazy" at home!

Well, her self-imposed exile will be ending tonight - Christina's gonna make an in store appearance at the Best Buy in Hollywood tonight at 7pm to promote her new DVD, Back to Basics: Live and Down Under!

Although she may be ready to spend some time with adults, Christina raved about baby Max, saying "it's still the first couple of weeks so every week something new happens" and that he's constantly doing new and stinky things"! Hey, that's what babies do!

She also admitted that since she "never knew a lot of Jewish people growing up," she had never heard of a Briss (the Jewish circumcision ceremony), until she planned her own, complete with penis balloons!

Christina also talked about Paris' accidental announcement of her pregnancy, saying she wasn't mad, she had just wanted to do it in her own time.

But Christina's not just the proud mama of baby Max, she's also excited about her new album, which she says "will have a whole new me -- a different me, so it's a lot to look forward to."

Sounds like Christina's got a lot to look forward to!
