Reportedly, the All Day singer served as a father figure for Kourtney Kardashian's children over the weekend.
As we previously reported, the Keeping Up With The Kardashian celebrity dumped her baby daddy when photos surfaced of Lord Disick getting cozy with ex-GF Chloe Bartoli on a yacht whilst in the South of France. Whoa!
It's said that while the mother-of-three stayed home with her kids Penelope and Reign, Mason accompanied Kim Kardashian West and her family to New York.
Seems the five-year-old spent his Fourth of July on a yacht owned by J.R. and Loren Ridinger. Not too shabby!
