John Legend Revs Up the Fun with Daughter Luna and Son Miles at F1 Las Vegas Grand Prix

John Legend revved up the fun with his kids!

The singer, 45, attended the Formula 1 Las Vegas Grand Prix on Saturday, Nov. 23, with his two eldest kids Luna Simone, 8, and Miles Theodore, 6.

The proud father shared a behind-the-scenes look at their time in Las Vegas on Instagram on Sunday, Nov. 24. “24 hrs in Vegas,” he captioned the post, which included photos of them participating in kart racing and other F1-themed activities.

Legend wore an all-black ensemble at the racing event. He dressed down in a pair of black slacks and a black T-shirt with a snakeskin black jacket. 

Luna rocked an oversized dark gray sweatshirt and animal-print pants, while Miles wore a blue, white and black plaid shirt with a bright blue beanie and distressed gray jeans.

Legend shares Luna and Miles with wife Chrissy Teigen, as well as Esti Maxine, 22 months, and Wren Alexander Stephens, 17 months.

In an exclusive interview with PEOPLE in September, the “All of Me” singer revealed which of his four children prefer him over Teigen. 

“Chrissy’s everyone’s favorite I think, except I might have Esti,” he revealed.

The Grand Prix took place from Nov. 21-23 along the Vegas Strip. The final two days of the event welcomed the first-ever daytime fan experience, which featured interactive activations, live entertainment and good trucks.

The star-studded event also attracted Shaun White, Nina Dobrev, Tommy Hilfiger, Jared Leto, Paris Hilton, Paul Mescal, Gordon Ramsay and more.
