Vanessa Hudgens and boyfriend Austin Butler couldn't keep their hands off of each other over the weekend.
The pair, who kicked off Saturday night by dining at new hotspot Hakkasan Las Vegas were joined by Kelsey Grammer and wife Kayte Walsh, who were all celebrating a mutual pal's birthday.
In a nearby private dining room was Ke$ha, who threw a surprise party for one of her creative directors.
Vanessa Hudgens burned some calories on Thanksgiving with a SoulCycle spinning class in New York's Union Square neighborhood.
"She was in the middle front row in cropped yoga pants, a pink tank top and a black sports bra," an onlooker tells PEOPLE.
Although she was "on her iPhone until the class started," once things got underway, she was "really bouncy and dancing to the music."
"She had a big smile on her face," the source adds.

"Abandon all hope ye who enter here," warns the sign greeting guests to the Gates of Hell – as if they even had to say it.
Welcome to Halloween Horror Nights at California's Universal Studios Hollywood, which, like its sister park in Orlando, Fla., decks itself out on select nights this month for that scariest of holidays. Having frightened brave-hearted visitors witless since 2006, Universal's multiple walk-through horror mazes include this year's newest attraction, a ghoul-filled Dead Inside zombie apocalypse inspired by AMC's The Walking Dead (whose third season premieres Oct. 14).
"You need to be emotionally involved in order to be drawn into the horror," Halloween Horror Nights creative director John Murdy, stepping over empty shotgun shells amid the piped-in ersatz scent of rotting corpses, recently told PEOPLE at the entrance to the Walking Dead maze, which features actual scenes and props from the series.
The Spring Breakers head north!
Selena Gomez, Vanessa Hudgens (and about 48 others from the cast of Spring Breakers) reunited for dinner – sans James Franco – in the private dining room at Brassaii Restaurant and Lounge in Toronto on Friday night.
"Selena was stunning and very excited about being here," an onlooker tells PEOPLE. "Both girls looked very elegant."
Upon arriving, Gomez took a slight detour before entering the restaurant.
"There were some young girls waiting on the red carpet set up outside. She sidestepped her handler and took some Thelma and Louise style photos with her fans," a source says.
"She also signed a 9-year-old boy's baseball cap ... and demanded Vanessa do the same."
"It was all very cute, she was so sweet to do it," the source adds.

It was a music-filled weekend in the forest for Vanessa Hudgens and boyfriend Austin Butler.
The couple braved the freezing cold weather in San Francisco's Golden Gate Park, where they attended Outside Lands, a music, food, wine, beer and art festival, set up like a wonderland in the wilderness.
Sitting on a blue tarp early Friday evening, Hudgens and Butler chilled out right before watching a set by Canadian electronica duo, MSTRKRFT.
"Vanessa was on her cell phone, while Austin laid down next to her, seeming super relaxed," an onlooker tells PEOPLE.
Ashley Tisdale rang in 27 with some of young Hollywood's biggest stars.
Set with a fête at a house in Malibu, the Miss Advised co-executive producer was joined by her man Scott Speer, along with Selena Gomez (who came solo, but brought some of beau Justin Bieber's pals) and Vanessa Hudgens and beau Austin Butler.
Sipping on Coco Brevé alcoholic beverages throughout the day, Tisdale and Speer showed "lots of P.D.A. action," an onlooker tells PEOPLE.
The birthday girl, clad in a yellow fringe bikini, and short jean cutoffs, took to Instagram to express her happiness over the celebration.
"Magical night at the beach!" she wrote, accompanying a bonfire photo. "#birthdaygirl."

Vanessa Hudgens didn't hold back when it came to putting her adoration for boyfriend Austin Butler on display at the Smoke & Mirrors Party at the Guess Hotel on Saturday in La Quinta, Calif.
"They held hands the entire afternoon," an onlooker tells PEOPLE of the couple, who were in town for Coachella. "They were extremely lovey-dovey."
But the smitten stars, who nibbled on vodka-filled snow cones, did take a break from their PDA-fest to munch on chicken and couscous – and grab a handful of complimentary sunglasses.
