Justin Bieber Brings Siblings To Join Selena Gomez In Toronto

Bieber chilled out with his girlfriend Sunday while she promoted several films at TIFF.

Justin Bieber showed girlfriend Selena Gomez some love in his home country of Canada. The singer joined Gomez at the junket for her film, "Hotel Transylvania," over the weekend.

An eyewitness tells MTV News that the superstar was on hand as Gomez promoted the film at the Toronto International Film Festival, popping in and out of the interview rooms, including Gomez's, on Sunday.

But, that wasn't the only Bieber that Gomez was spotted with while in town to rep her animated family flick, as well as the much darker, much older "Springer Breakers." Bieber's baby brother and sister, Jaxon and Jazmyn, were by Selena's side on Saturday for the premiere of "Hotel Transylvania," which also stars comedy A-listers Adam Sandler, Andy Samberg, Kevin James, Molly Shannon and Fran Drescher.

That same day Bieber tweeted about landing in Toronto. He wrote, "Feels good to be back. #home." But it would be one day before the most famous of the Bieber siblings would be spotted with Gomez during TIFF.

In addition to being her official cheerleader while she's out promoting her latest slate of films, Bieber also wrote a song for the VMA-nominated Gomez for her next album. His pal will.i.am confirmed the collaboration earlier this summer.

"He taps me on the shoulder ... 'Yo, I want to show you this song I produced and wrote. I'm really excited about it because it's one of the first songs I produced by myself,' " will.i.am recalled. "The song was dope. He was like, 'Yeah, I wrote it for Selena. It's great.' And it was really awesome. It was really, really dope."

Gomez is not only working on new music, but she also has a roster of other flicks to keep busy with including "Parental Guidance Suggested," "Aftershock" with Eli Roth and the Ethan Hawke thriller, "Getaway."
