East is touring as Stapleton's opener and at their Los Angeles stop at the Greek Theatre on Wednesday night, Stapleton asked Lambert to come up and join in on the performance.
"I've got my girl and you've got yours, it works out," Stapleton quipped to East. "She's gonna whip my ass later."
Lambert also took in East's set from the side of the stage. Later, the pair watched Stapleton perform while sharing kisses and enjoying a couple of drinks.

The pair went public with their relationship in December, five months after she and Blake Shelton announced they had divorced. East and Lambert also made their red carpet debut earlier this month at the ACM Awards in Las Vegas.
