Jennifer Aniston made the morning show rounds for Just Go With It in NYC today. She stopped by Good Morning America to talk about her famous Rachel haircut and also visited The Early Show with anchor Erica Hill. Erica brought Jennifer a few early gifts, including Snooki's new book and a wig, ahead of her 42nd birthday tomorrow, since Jennifer has apparently been hooked on Jersey Shore since the first episode. Another of MTV's reality stars, Heidi Montag, makes a cameo in Jen's romantic comedy. Heidi, however, wasn't at the star-studded premiere on Tuesday and is now saying she was absent after being banned from the event by Jen herself.
