What cheating rumors? Will Smith and wife Jada Pinkett Smith showed no signs of strife between them when they celebrated Will's son Trey's 21st birthday in Las Vegas on Sunday, Nov. 10, amid persistent chatter about the Men in Black 3 actor's relationship with his Focus costar Margot Robbie.

Dining with Trey and kids Jaden, 15, and Willow, 13, at Sin City hotspot Hakkasan, the spouses of 16 years looked just as happily married as ever. Their group of about 50 family members and friends feasted on dishes including crispy duck salad, Hakka steamed dim sum, Mongolian-style beef tenderloin, and more.

A source tells Us Weekly the energy in the room was "lively and filled with laughter." Will and Jada, in particular, "were in high spirits, rarely leaving one another's side," the source adds. They even snuck a few happy moments together away from the rest of the revelers.

Toward the end of the meal, the source tells Us, Will got on the mic to "say a few special words in honor of the birthday boy." From there, the whole family — including Trey's mom, Sheree Zampino — moved on to another hotspot, LAVO, where they kept the party going with music, cake, and dancing. (Trey's underage half-siblings enjoyed a live feed of the action nearby in LAVO's restaurant.)

A second source tells Us that Trey manned the DJ booth for a bit, spinning a mix of electronic dance music that got the whole crowd moving. At around midnight, his dad interrupted to wish his son a happy birthday, and the club presented Trey with a cake.

The spirited fete comes on the heels of rumors that the After Earth star, 45, was cheating on his wife, 42, with his 23-year-old costar. Robbie herself slammed the rumors as "ridiculous" and untrue on Twitter, and a source further confirmed to Us that the longtime Hollywood couple were still going strong.

"Everything with them is great," the insider said of Will and Jada.

Indeed, the Hawthorne alum seemed grateful for her many blessings earlier on Sunday. "Thank you Higher Power for giving me yet another day with an opportunity to…live," she wrote on Facebook. "My father would often say, 'Nobody gets out of life alive.' His words linger in my head as a reminder to live every day to the fullest and to live a life that is deeply meaningful. This is my wish for us all. Happy, happy Sunday, everyone."
