It was couple’s night at Us Weekly’s Hot Hollywood bash at NYC’s Skylight Studios on Tuesday night.

Vanessa Hudgens helped beau Zac Efron celebrate his Star of the Year honor.

"He’s doing really great things, and it’s fun," she told Us. "Ashley [Tisdale] is here too, and Monique [Coleman] as well, so I get to be here with my High School Musical family!"

Of being named Star of the Year, Efron told Us, "It’s been a busy year so far - a lot of us have been working really hard, so it’s very flattering."

 Those weren’t the only chummy co-stars.

CW’s Gossip Girl was named Cast of the Year.

"A year and 1/2 ago nobody really knew who we were, and now we’ve risen to this!" said Penn Badgley, who arrived with girlfriend Blake Lively. "It’s a lot of fun for all of us."

(Before they left together, Lively gave Badgley a kiss on the lips!)

Which celebs was Becki Newton dying to see?

"Everyone!" she gushed to Us.

She and her Ugly Betty costar Michael Urie were named Comedy Duo of the Year.

"Anytime Becki and I get to do anything together, it’s really fun," Urie told Us. "And when we’re honored for our work, it’s really so nice."
