At the time, a source told Page Six that Suri was "showing praise for her mother" by using Noelle Holmes' middle name.The source added that the then-teen wanted to "avoid the paparazzi," establish her "own identity" and “start fresh at college.”However, according to People, Cruise's limited time with Suri after his 2012 divorce from Holmes had also come under scrutiny earlier. In a 2013 deposition tied to his lawsuit against Bauer Publishing, Cruise admitted he didn't see Suri who was then 7 and half, in person for over 100 days.During the same deposition, Cruise revealed Suri was no longer practicing Scientology. When asked if Holmes left him to "protect" Suri from the religion, he said, "I find that question offensive. There is no need to protect my daughter from my religion," though he admitted it was "one of the assertions" behind the divorce.Also Read: Bryan Kohberger update: Why does the Idaho murders convict want to withdraw his guilty plea?
