Beyonce's Baby Blue Ivy Carter Home Again while Bey Parties at Jay-Z Concert (Video)

Beyonce's baby Blue Ivy Carter was left at home once again as Bey partied it up during her husband, Jay-Z's concert. The singer has been spotted out more and more lately as Blue Ivy's gotten older.

This time, the 30-year-old showed her Hov support during Radio 1's Hackney Weekend when he was performing. He was joined by an assortment of talents, from Rihanna to M.I.A. to Kanye West. Bey got cream-of-the crop treatment and was spotted enjoying the concert in front of the stage. Those are just the perks that come along with being Mrs. Carter.

In the video below, you can see Beyonce joining in the mosh pit during Jay-Z's N---as In Paris. The wet weather did little to dampen Bey's mood. Of course, she may have missed her baby Blue Ivy, but her mood wasn't blue. She obviously had a blast and really enjoyed herself during her break from mommy duty.
