“It’s our bachelor party as much as it’s for him. It’s really for all of us,” said Nick, 25. “We got no plans yet, [but] it’s gonna be very respectful. We’re gonna have some fun. We have to! He’s gonna get married. It’s a big deal.”

The entertainer also turned heads on the carpet with his form-fitting dress shirt that accentuated his bulging biceps.

After Joe, 28, and fiancée Sophie Turner, 22, announced their engagement last year, Nick gushed about his future sister-in-law.

The engaged couple began dating in late 2016 and had a whirlwind romance before Joe popped the question last October.

“Everybody’s very, very happy for them and their family and friends are all thrilled. Everyone loves them together,” a source previously told PEOPLE of the exciting news. “She’s young but is beyond her years and is crazy, crazy mature. He’s never been like this with a girl.”
