Olivia Rodrigo Wishes ‘Angel Boy’ Louis Partridge a Happy Birthday

Louis Partridge turned 21 years old on Monday (June 3), and Olivia Rodrigo celebrated the actor with a sweet Instagram comment.

The Enola Holmes star took to the social media platform to share a throwback photo of himself as a child, rocking a French-style mustache. “One beer s’il vous plaît,” he wrote in the caption.

“Welcome to the 21 club angel boy!!!!” the “Vampire” wrote in the comments section. The comment currently has more than 100,000 likes.

Rodrigo and Partridge first sparked romance rumors back in October when they were seen spending time together in London, walking seemingly with their arms wrapped around each other’s waist. The Enola Holmes star was also seen supporting the “Get Him Back!” singer at iHeartRadio’s Jingle Ball in New York City on Dec. 8, and again one day later when she served as the musical guest on Saturday Night Live.

Rodrigo’s Guts deluxe track, “So American,” is rumored to be about the actor, as she sings in the chorus: “I’d go anywhere he goes/ And he says I’m so American/ Oh God, I’m gonna marry him/ If he keeps this s–t up/ I might just be in love.”

The superstar is gearing up to to head out on the Asian leg of the Guts World Tour, which kicks off Sept. 16 in Bangkok, Thailand, and will find Rodrigo traveling through Seoul, Hong Kong and Tokyo. Soon afterward, Rodrigo will play two shows in Melbourne followed by two in Sydney in October. She’ll be joined for all four Australian shows by rising alt-pop star Benee.
