The 49-year-old actress and Lee, 21, stepped out on Saturday at the Shepherd Conservation Society’s 40th Anniversary Gala for the Oceans in Beverly Hills, California, and traded smiles on the red carpet as they posed for several photos. They later continued to pose for photographs inside the event.
Anderson sported a red, draping jumpsuit by Gauri & Nainika with her blonde locks hanging over her left shoulder. Meanwhile, Lee served a look similar to that of his rocker father Tommy Lee.
Lee wore a white shirt with sleek, black pants.
He topped off the look with a pair of shining, silver shoes and sunglasses.
Anderson shares two sons, Brandon and Dylan, with the 54-year-old musician.
The Crazy Cost of a Lifetime of Beauty
The outing comes after Lee and his father took Las Vegas by storm over the weekend in a birthday celebration for Lee, who turned 21 on June 6. On Thursday, Lee brought his girlfriend Pyper America Smith to Intrigue Nightclub, where they partied at a stage table to watch their pal Diplo spin for the crowd.
And on Friday, they headed to Encore Beach Club and took shots before continuing the party at XS later in the night.
On Saturday, both Lee and Tommy shared a photo of themselves lounging in front of a jet, appearing tired from the festivities.
“We make it through the Weekend,” Lee captioned the shot. “Great way to wrap up my Bday.”
