The whirlwind romance took off quickly after the pair confirmed their relationship in May, but it appears that it may not be smooth sailing for long.
A source from Us Weekly recently revealed that Munn and Mulaney have had “an imperfect relationship from the start,” after perhaps moving things along too quickly.
In September, the SNL comedian, 39, announced during an appearance on Late Night with Seth Meyers that he and the Newsroom alum, 41, were expecting their first child together after having only been together for less than a year.
But as they prepare for the arrival of their new bundle of joy, Munn’s close friends are concerned about the long-term future of the fast-moving relationship.
The source told the outlet, “Even though Olivia’s going to be a wonderful mother and has great support behind her, Olivia’s friends just don’t see these two being a couple in a year’s time.”
While the source noted that the pair will “make great parents,” they added that “nobody knows yet if they’re going to do that together or apart.”
The stand-up comic also appeared to still be figuring his life out as he revealed to Meyers in September that he started off the year in and out of rehab before getting together with the Predator actress.
The pair is now rumored to be headed for a breakup due to “uncertainty” in their swiftly established romance.
“Olivia and John still have to decide what kind of future they’re going to have together, if any,” the source added. “It’s a time of uncertainty, for both of them.”
They added that the soon-to-be parents “are a long way from deciding and locking in what their relationship is going to be going forward.”
Mulaney’s hook-up with Munn came on the heels of his split from wife Anna Marie Tendler, who he was married to for six years.
The comic filed for divorce in July, just two months before confirming that his new flame was having his baby, which he said they were “really, really happy" about.
The New Girl alum revealed in September that the future mom-and-dad still weren’t sure if they wanted to know the sex of their baby before giving birth.
"I haven't decided if I'll find out yet or not," the actress said at the time. "It's a good surprise to find out. There's very few surprises in life."
