Justin Bieber has never been afraid to express his love for his BFF and "big sis" Selena Gomez, but have the teen duo taken their friendship to the next level?

Justin and Selena were spotted leaving a pancake parlour arm-in-arm over the weekend, but according to onlookers, that's not all they did.

Customers inside the restaurant told TMZ that Justin and Selena were holding hands and looked "cuddly" as they sat together in the booth.

We wonder what Jasmine Villegas thinks about her man cuddling up to the Disney starlet.
