Nobody Wants This Star Justine Lupe and Tyson Mason Marry in Courthouse Wedding with Their Baby Daughter Ellis (Exclusive)

Justine Lupe has tied the knot!

The Nobody Wants This star, 35, married Tyson Mason in a courthouse ceremony in Beverly Hills, Calif., on Tuesday, Feb. 18, Lupe's rep confirms to PEOPLE. The couple was joined by their baby daughter, Ellis, and their dog.

Lupe wore an ivory satin, floor-length slip dress for the occasion and carried a small bouquet of flowers. Mason sported a classic black suit. Ellis, who was born in August 2024, wore a frilly white dress, and the couple's pup even got in on the action, sporting a mini tuxedo.

Although it's unclear exactly when the couple first began dating, the Succession star has shared posts with Mason on her Instagram since August 2023. In January 2024, he accompanied his now-wife to the HBO post-Emmy Awards celebration. At the time, the actress joked on Instagram that he agreed to join her "because there was a promise of no dancing."

When Nobody Wants This premiered on Netflix on Sept. 26, Lupe shared a post revealing that she was more than five months pregnant while filming the series — and even tried to hide her pregnancy from the show's cast and crew for a while.

"Nobody Wants This is out on @netflix today! This show carried me through my first 5+ months of pregnancy with so much warmth," she wrote in the post.

She went on to express her appreciation for "having a fully pregnant showrunner in @erinfoster, a relentless champion for motherhood in @kristenanniebell, a DP in @adrianpengcorreia who knows how to work the shit out of camera to make me look, well, not pregnant."

Lupe then recounted how her costars and the crew learned she was expecting a baby. "And a cast and crew who supported me from the moment my Gucci skirt ripped open in both the front and backsides on set at 2am when they had no idea I was pregnant and thought I was just rapidly falling apart," she continued.

On Feb. 6, Lupe took a moment to mark six months of parenthood, while giving a sweet shout-out to Mason on Instagram. Alongside a series of photos and clips of Mason, the couple and their daughter, she wrote: "SIX MONTHS in the trenches with you and boy oh boy baby you’re the prize. 🏆♥️."

Back in August 2023, the Marvelous Mrs. Maisel star posted some sweet photos on Instagram of herself and Mason — including a shot where she's planting a kiss on his cheek. In another lighthearted, side-by-side snap, she jokingly compared Mason's facial expression to a baby bear.

"You you you ♥️," she wrote, sharing her love for Mason.
