Natalie Portman, 42, can’t stop smiling with Paul Mescal, 28, in London after Benjamin Millepied divorce

Is she in a “May December” romance of her own?

Natalie Portman appeared giddy while hanging out with Paul Mescal in north London on Tuesday.

The “Black Swan” star, 42, was seen laughing while engaged in a lively conversation with the “All of Us Strangers” actor, 28, outside of cocktail bar 69 Colebrooke Row in Islington.

Mescal also seemed to be enjoying his time with Portman, as he was spotted at one point grinning from ear to ear while looking flushed with bright red cheeks.

The “No Strings Attached” star — who is newly divorced — was dressed casually for the outing in a white T-shirt and pair of comfortable jeans. She nonchalantly puffed on a cigarette during the cheerful chat.

The “Foe” star wore a similar outfit, sporting a white tee, a pair of black slacks and matching sneakers.

According to an eyewitness, the pair seemed to have “great chemistry” and “couldn’t stop laughing at each other’s jokes.”

Reps for Portman and Mescal did not immediately respond to Page Six’s requests for comment.

However, multiple outlets — including People and TMZ — reported that the famous duo are just friends.

The actors could take their relationship to the next level, though, as they are both seemingly on the market.

Portman quietly filed for divorce from her ex-husband, Benjamin Millepied, in July 2023 following rumblings that he had been unfaithful with a younger woman named Camille Étienne.

The former couple — who share son Aleph, 12, and daughter Amalia, 7 — finalized their split in February.

Although it was reported that the “Closer” star had a really tough time with the dissolution of her marriage in the beginning, Page Six exclusively learned by March that she was having a “phoenix rising” moment.

“[She] looks incredible and is feeling great,” a pal of Portman told us at the time.

Mescal, for his part, was most recently in a high-profile romance with Phoebe Bridgers.

However, the “Aftersun” star and the “Not Strong Enough” singer sparked split rumors in late 2022.

He was then seen going to grab coffee with Angelina Jolie, further fueling the breakup speculation.

By May 2023, Bridgers confirmed she had moved on when she was seen kissing Bo Burnham at a show on Taylor Swift’s Eras Tour.
