Justin Bieber’s manager Scooter Braun and cancer activist Yael Cohen tied the knot in Canada last weekend.

On Friday Braun tweeted, “Going to be an epic weekend. Happy 4^th!” After the wedding Bieber posted a message for the couple on Instagram saying, “can’t believe Scooter found someone that puts up with his bs 😉 love you guys.”

The ceremony took place in Whistler and several celebrities attended including Bieber, Carly Rae Jepsen, Tom Hanks and wife Rita Wilson, Ed Sheeran, and Sophia Bush.

Bieber serenaded the newlyweds with The Beatles’ “All You Need Is Love,” as they shared a kiss in front of family and friends. However, that was just the beginning. Bieber, who was dressed in a black suit with a matching hat, also sang “Call Me Maybe” with singer Carly Rae Jepsen.

The two singers weren’t the only ones having fun during the reception. Bieber also posted a video of actor Tom Hanks on Instagram dancing to the tune of Montell Jordan’s classic hit “This Is How We Do It.”

Bieber posted another picture on Instagram with Sheeran with the caption, “@edsheeran is one of the only people on my iPod.”

Asher Roth and Ed Sheeran also went up on stage and did their own rendition of Blackstreet’s “No Diggity.” Who needs a wedding band when you have chart-topping singers as your wedding guests, right?

Braun and Cohen have been dating since 2013, and while there was no announcement on when they were engaged, Cohen posted a “yes” neon sign on her Instagram in January saying, “Been terrible at posting over the last week, feel like this sums it up nicely.”

Braun, 33, is a talent manager who represents Bieber, Jepsen, Psy, and The Wanted. He also owns two record labels – Raymond-Braun Media Group (RBMG) and School Boy Records. Canadian-native Cohen, is the CEO and founder of F**k Cancer, a health organization dedicated to working for prevention and early detection of cancer.
