Luna was born in 2012 during Uma's relationship with Busson (the pair were together from 2007 to 2009 and then again between 2011 and 2014). Not much is known about the 8-year-old, but she was the reason behind the pair's custody battle a few years back. In early 2017, Uma won primary physical custody of her then 4-year-old daughter. Luna has made some appearances in Levon and Maya's Instagram accounts, so it appears that she is close with her older brother and sister!
