Justin Theroux welcomes first baby with wife Nicole Brydon Bloom

Justin Theroux is a dad!

The “Leftovers” alum’s wife, Nicole Brydon Bloom, has given birth to the couple’s first child.

“He’s here 🕊️ we are so in love,” Theroux, 54, and Bloom, 32, said in a joint Instagram post on Saturday.

The parents revealed the good news with a touching black-and-white snap showing the newborn baby lying on Theroux’s chest.

The couple revealed in December 2025 that they were starting a family, with the “Gilded Age” star debuting her baby bump at the “Fallout” Season 2 premiere.

The following week, Theroux subtly celebrated the news via Instagram.

“What an incredible holiday season so far…🌎🎄❤️,” the actor, 54, captioned a mirror selfie with his partner’s bare stomach on display.

Bloom, 31, gave more glimpses of her budding belly in an Instagram slideshow documenting the couple’s babymoon later that same month.

“So much fun to revisit our favorite place with a little one on the way 🕊️👶🏼,” the then-pregnant star told her followers at the time.

Bloom proudly posed with her “plus one” at the Critics Choice Awards 2026 red carpet the following month.

She and Theroux have been married since March 2025, tying the knot in Mexico after two years of dating.

The duo were first romantically linked in 2023.

Theroux got down on one knee the following summer while the pair were in Italy for the Venice Film Festival.

The “Girl on the Train” star has been married once before, to Jennifer Aniston.

Four years after the former couple’s 2018 divorce, Aniston opened up to Allure about struggling to conceive children via in vitro fertilization in her late 30s and 40s.

“The ship has sailed,” the “Morning Show” star told the magazine at the time. “There is no more, ‘Can I? Maybe. Maybe. Maybe.’ I don’t have to think about that anymore.”

Theroux made headlines for commenting on the “Friends” alum’s cover story promo with fist bump and heart emojis.

The exes have remained amicable since their split.

“We don’t talk every day, but we call each other. We FaceTime. We text,” Theroux explained to Esquire in 2021. “I’m sincere when I say that I cherish our friendship.”

He even “liked” Aniston’s recent Instagram hard-launch with her boyfriend, hypnotherapist Jim Curtis.
