A kiss for the birthday girl!

Bill Hader and Ali Wong didn’t stray from PDA while celebrating the actress’ 41st year on Wednesday.

In the pair’s first photographs together, obtained exclusively by Page Six, the normally low-key couple looked loved-up on a hike and even shared a smooch.

The “Beef” star wore an all-black outfit and a straw hat as she and Hader, 44, held hands walking near her Los Angeles home.

Wong and the “Saturday Night Live” alum, who paired a red shirt with gray sweats, were all smiles and laughed throughout the hike.

Later that same day, the duo stepped out again for a romantic dinner date.

While Hader kept his outfit casual in a black shirt and matching jeans, Wong wowed in a colorful dress, gold earrings and a puffy headband.

Page Six confirmed on Monday that the on-again, off-again couple were back together after a short-lived romance in 2022.

While the pair have yet to address their relationship status, Hader did gush about his “girlfriend” during a new Collider interview.

The actor credited Wong with pushing him to take a trip — which will be his first in 10 years.

“I went with her to San Francisco, but that doesn’t really count,” Hader explained to the outlet. “So, I’m going to have a vacation.”

The “Barry” star was previously linked to “Hart of Dixie” alum Rachel Bilson and “Pitch Perfect” star Anna Kendrick in recent years.

As for Wong, the stand-up comedian was married to businessman Justin Hakuta from 2014 to 2022.

The former couple, who share daughters Mari and Nikki, have kept things cordial since calling it quits.

Wong even referred to Hakuta as her “best friend” while speaking to the Hollywood Reporter in March.

She called their divorce an “unconventional” one at the time, noting, “We’ve been through so much together.”
