Wilmer Valderrama has a little girl on the way.

The That 70's Show alum, 40, and his fiancée Amanda Pacheco revealed the sex of their first child together on Thursday, hyping the announcement on Instagram with a teaser before sharing a throwback video montage of the sex reveal party "from early 2020."

"Boy or Girl? Place your bets on that comment bar...Reveal in 45mins...," wrote Valderrama, sharing a snapshot of himself posing with Pacheco amid blue and pink smoke.

"Wolf or Mermaid? 'A moment that will live in our hearts, the instant we found out that we were having a ______ !' #ItsJustUs3Now," he then wrote along with the video, which sees an outdoor gathering of people looking to the sky as a parachuter jumps from a helicopter and spreads pink fog behind himself, signifying a girl.

Those in attendance cheer at the revelation, as the parents-to-be are pictured kissing to celebrate. At one point in the video, Pacheco is heard telling a friend, "I told you it was a girl! I looked you right in the eyes and said it's a girl!"

A message at the start of the video says everyone followed "guidelines and took necessary precautions to ensure our safety and the safety of our close friends and family" at the outdoor event.

The note also adds the entire home was "sanitized and every guest was tested before and after the gathering, all with negative results."

'That said, with the rising number of cases in CA, please know that we have not since had or attended any large gatherings nor do we encourage people to do so. Please wear a mask and be safe," the message adds.

The couple, who became engaged in January 2020, announced their pregnancy news last month.

Though her baby bump isn't visible in the throwback sex reveal video, Pacheco shows off her pregnancy figure in photos recently shared, including one that sees Valderrama embracing her. "Holding our precious little..._____!!Boy or girl ?!😬," she teased Thursday in the caption.
