Olivia Munn and John Mulaney are "still dating," a source told E! News (opens in new tab).

They are expecting a child together, which is something Munn has wanted for some time, but sources say she doesn't much care if she and Mulaney co-parent as a couple or not.

"Being a mom was always more important to her than settling down in the traditional way," the source told Us Weekly (opens in new tab).

The source added, "She is incredibly choosy and John is someone she would definitely want to get to know if and when they ever become single. John is much more immature than Olivia, but Olivia needed this change in her life. She had been stuck in a rut for the past few years. This changes things and gives me something to focus on besides my career and social life."

Mulaney announced his divorce from Anna Marie Tendler last spring and began dating Munn shortly thereafter. He announced that they were expecting a baby together in September during an appearance on Late Night With Seth Meyers (opens in new tab).

Munn is starring in the film "Violet" (opens in new tab), which will be released on October 29 and available on demand on November 9, and Mulaney is preparing to do a stand-up show (opens in new tab) on November 16 and 17 in Long Beach, Calif. (opens in new tab).
