Melissa McCarthy was fangirling over Billie Eilish at the 2024 Screen Actors Guild Awards.

While presenting the award for outstanding performance by a female actor in a comedy series to Ayo Edebiri (The Bear), the Little Mermaid actress, 53, hilariously asked the pop star, 22, to sign her face with a permanent marker.

Prior to the autographing, McCarthy reminded Eilish that the pair had already met several times prior to the SAG Awards, which streamed live on Netflix from the Shrine Auditorium in Los Angeles on Saturday (Feb. 24).

“I actually met you in utero because your mom was my first improv teacher,” McCarthy said excitedly, referring to Maggie Baird. “Guess who she was pregnant with? It was you!”

“Wow, OK,” Eilish responded. “That’s a lot.”

McCarthy then asked the “Bad Guy” singer if she would sign her shiny colored gown. “I’m just trying to be more present in making memories and I’m trying for more YOLO-ing and less FOMO-ing,” McCarthy said.

When Eilish politely declined, the actress made an even more bizarre request: to sign her face instead. The singer agreed and proceeded to scribble her signature on McCarthy’s forehead with a black Sharpie.

As the actress attempted to ask more questions about her brother Finneas’ songwriting process, Eilish covered her mouth and attempted to contain her laughter.

“So, when you and Finneas are putting down sick tracks or hot, hot beats…,” McCarthy’s began to ask. “I think that’s better,” the singer replied while holding her hand over McCarthy’s mouth.

The big winners at the SAG Awards included Cillian Murphy (Oppenheimer) and Lily Gladstone (Killers of the Flower Moon), who took home outstanding performance by a male and female actor in a leading role, respectively. Both won in what were seen as close races with Paul Giamatti (The Holdovers) and Emma Stone (Poor Things), respectively.
