Stephen Colletti Is Going to Be a Dad! ‘One Tree Hill’ Star and Wife Alex Weaver Expecting First Child

Fans of the One Tree Hill heartthrob have a big reason to celebrate in 2026: Stephen Colletti and his wife Alex Weaver are expecting their first child together, just three months after tying the knot in a romantic October 2025 wedding. The joyful announcement — shared in a pair of intimate black-and-white Instagram photos — has sent social media into a frenzy and marked an exciting new chapter for the beloved actor and his NASCAR host wife.

A Beachside Reveal With Big Heart Emojis

On January 20, Colletti and Weaver took to Instagram to share the news. In one of the photos, the couple stand on a beach holding hands, while the second snap beautifully showcases Weaver’s baby bump as she places one hand on her belly and Colletti holds her from behind. Their caption was sweet and simple: “Mom & Dad 🤍” — a statement that’s already trending across entertainment feeds and pop culture timelines.

Colletti himself joined in the excitement with a playful Instagram comment consisting of two emojis — “🐣🤗” — signaling both anticipation and joy.

From ‘One Tree Hill’ to Real-Life Romance

The news reflects not just expanding family life, but the personal journey that brought the couple here. Colletti, 39, rose to fame on One Tree Hill as Chase Adams, while Weaver, 32, is known for her work as a NASCAR host and reporter — a blend of genres in which fanbases have increasingly rooted for their union.

The couple began dating back in 2021 and announced their engagement in Rome in November 2023, a moment Weaver later described as “completely unaware of what was about to happen” when Colletti popped the question in the Giardino degli Aranci.

Just months later, on October 3, 2025, they married in a “beautifully intimate” civil ceremony surrounded by close family. As they previously told People about their courthouse wedding, “It was a beautifully intimate day that was celebrated with both of our families by our side.”

Fans and Friends Flood the Feed

Celebrities and former co-stars alike have already chimed in with congratulatory messages. On social feeds, Colletti’s Laguna Beach and The Traitors costars joined fans in celebrating the news, with comments ranging from “Congrats!!!” to heartfelt emoji-filled reactions.

This broad outpouring of support highlights just how cherished Colletti’s cultural journey has been — from MTV’s Laguna Beach to CW drama and primetime reality TV — now culminating in an announcement that transcends entertainment and touches fans’ hearts everywhere.

What This Means for Fans and Pop Culture

For many viewers who grew up watching Colletti, this news feels like a personal milestone. It’s a reminder of how early-2000s TV stars have transitioned into full-fledged adult lives — paired with careers, families, and fan communities that have grown alongside them.

Entertainment outlets are already calling this one of the feel-good celebrity announcements of the year — and with good reason. Between their personal love story, heartfelt social media moment and months of speculation leading up to this reveal, the couple’s pregnancy announcement is capturing the attention of audiences both inside and outside Hollywood.

As fans continue to rally behind Stephen Colletti and Alex Weaver, one thing is clear: the One Tree Hill alum’s next role — that of father — is set to be his most meaningful yet.
