Justin Bieber's not shy of some lighthearted Instagram trolling at the moment and his latest jibe was aimed at wife Hailey, or, more specifically, her boobs.

Justin Bieber's been playing about on Instagram lately, and he's turned his attention to new wife Hailey Baldwin's page, dropping a cheeky comment on a photo she posted with pals Kelia Termini and Laura Lentz asking if her boobs were in fact her knees pushed up through her shirt.

The singer, who is rumoured to be currently be working on his fifth album, also got into hot water over Christmas for leaving a shady comment on dance star JoJo Siwa's picture, telling her to 'burn' her pretty garish custom car, which he later apologised for.

It seems like a happy Justin is a an active Instagrammer, but he isn't only online for the jokes as he also praised his wife for opening up about battling anxiety and being 'insecure, fragile and hurt', commenting on her heartfelt post 'this is beautiful hun'.
