Ty Dolla $ign allegedly tried to get a blind woman moved from her seat on board his flight to Ottawa over the weekend because he was ''allergic'' to her guide dog.

The 33-year-old rapper - whose real name is Tyrone William Griffin Jr. - was on board an Air Canada flight from Montreal on Saturday (23.06.18) when he allegedly asked the unidentified woman, who was sat behind him, if she could move further back because the fur from her assistance pooch made him sneeze, according to TMZ.

The woman reportedly offered the 'Or Nah' hitmaker an allergy pill to help with his itchy nose, but he refused and claimed he had to perform on stage later that day.

Staff on board the aircraft attempted to calm down the situation by asking Ty if he had spoken to medical at the desk prior to boarding about his allergy, but he hadn't.

However, because the blind woman had got approval to take the dog on board when she booked her tickets, the flight attendants said she didn't have to move.

They did, however, offer the rapper a seat at the back of the plane, but he reportedly turned it down because he had paid extra for the place he had been allocated.

It's not known whether Ty's girlfriend Lauren Jauregui was on board with him.

The pair met after they collaborated on the Fifth Harmony song 'Work From Home' in 2016 and, although it was obvious they were together, they played down the rumours.

Asked whether they were dating in 2017, Lauren said: ''We're just, you know what I mean - we're just vibing. I don't want to talk about that.''
