Justin Bieber's mother has sparked rumours she's unimpressed by his engagement.

The 'Sorry' hitmaker recently announced that him and his on/off girlfriend Hailey Baldwin are set to walk down the aisle after he got down on one knee during a romantic getaway at the beginning of the month, but some eagle-eyed fans have started to speculate that his mom Pattie Mallette is against his drastic life update.

Pattie has always had "Yes, Justin Bieber is my son" in her bio on Twitter but just hours after the 24-year-old singer announced his engagement, she wiped it.

Fans then began tweeting Pattie asking her if she disapproves of his new relationship status, to which she simply wrote: "If you don't have something nice to say..."

She then poured even more fuel on the fire when she started liking random posts about rush engagements - although none of them referenced Justin and Hailey.

Former US 'Bachelor' star Sean Lowe said: "Before proposing to a woman they've only known for a few weeks, I think the final guys on The Bachelorette should come help me scrub my kid's diarrhea out of my living room rug just to make sure they're serious about the whole "I want a family with you" thing. (sic)"

It comes after Justin uploaded a gushy post on Instagram claiming that he couldn't wait to settle down with the model and show his siblings the true meaning of love.

However, it's unusual for Pattie to dislike Justin's partners as she previously said she "loves" his ex-girlfriend Selena Gomez, even though the pair were very on and off.

She said: "I don't know so much about their personal relationship because he doesn't share a whole lot, but I love her. I support anything [he does], if he loves her I love her, and I've met her and we have a special bond so I think she's precious. I can't really speak on their relationship, that's between them."
