Justin Herbert wasn’t going to let Madison Beer‘s birthday come and go without a heartfelt shoutout … as the Chargers quarterback wished his girlfriend a very special day on his Instagram, calling himself “the luckiest guy alive.”

“Happy birthday to my favorite person of all time,” Herbert wrote on Instagram. “I love you so much, you’ve changed my life forever.”

He included some photos of their outings together over the last few months. While it’s unclear when the two officially started dating, rumors began circulating in August 2025 when Herbert was seen at a video shoot for Beer.

We then saw them arrive at a friend’s house in Redondo Beach, California, later that month — and the two appeared quite cozy.

Since then, we’ve spotted the couple out and about, including sitting courtside during a Lakers game in October, where Herbert went into protective mode to shield the Long Island native from an errant basketball.

Of course, Beer showed support at some Chargers games this season — embracing the WAG role.

It’s unclear how Beer celebrated her 27th birthday, but she did share a mouthwatering cake on her own Instagram Story — suggesting some sort of gathering took place.

Hope it was a fantastic day, Madison.
