Christina and Brit all Grown Up

Christina and Britney are no longer pop rivals. The two have patched things up by exchanging wedding and baby gifts. Christina insists she's absolutely thrilled for Britney's success and there's no longer a feud between the two girls now that they're all grown up. Here's more from Christina:

"She got me a really beautiful crystal vase and a little crystal bucket that you can put drinks and champagne in (when I got married). "And when she had her baby, I sent over a huge baby basket. I didn't know whether it was a boy or a girl yet, so I sent over just something really sweet, something cute."
