Which Pop Star's Big Brother Is Made in the Shades?

This supportive Canadian sibling touched down for a little quality time with his famous newly single little sis—so who is he?

He's with the band. Well, the singer.

Now that his sister's love life has gotten a little less complicated, this supportive big brother has swooped in to offer some moral support. He was spotted dropping off his rocking little sis at the Beverly Hills Four Seasons over the weekend.

That's a long way from their native Canadian home. But hey, at least there's one boi in her life she can count on.

So whose big bro is this?

It's Avril Lavigne's brother dearest, Matthew!

He was seen escorting his little sis to her hotel on Sunday.

Avril recently split from longtime beau Brody Jenner, but at least it's paved the way to spend more quality time with her fam.

See? There's always a silver lining.
