Thanksgiving weekend was family time for Christina Milian and Kelis. The two moms put work on hold to take their children to see “Yo Gabba Gabba! Live! There’s a Party in My City!” at the NOKIA Theatre L.A. LIVE. Kelis’ son Knight Jones, looking every bit like his father Nas, had his picture taken with the Nick Jr. show characters, while Christina’s daughter Violet Nash couldn’t keep her tiny hands off green monster Brobee.
