Christina's Collaborating With Aretha!

Christina took her bump and full face of makeup on a couple more shopping excursions for baby stuff in L.A. She left Jordan home the first time around, but then let him join in on the fun. Jordan may be Christina's favorite person to collaborate with in her personal life, but apparently she'll partner with another person in her work world. Rumor is she'll be teaming up with Aretha Franklin for a duet. We've gotta hand it to Christina — for a mommy-to-be, she certainly doesn't seem to be letting her pregnancy slow her down very much.
