Rashida Jones and Vampire Weekend frontman Ezra Koenig welcomed a baby boy last month, People magazine reports.

The couple -- who were first spotted together in January 2017 at the Sundance Film Festival -- reportedly had the baby on Aug. 22 and kept the news under wraps until Wednesday (Sept. 26). According to People, the baby's name is Isaiah Jones Koenig. Us Weekly first reported the news.

While they weren't reported to be dating until last year, the pair have known each other for some time: Jones -- daughter of legendary producer Quincy Jones and actress Peggy Lipton -- appeared on Koenig's Beats 1 Radio show back in 2015 and talked about asking a teenage Robin Thicke to a school dance before abruptly rescinding the invitation.

"I was 12, 13. His dad was on Growing Pains and my mom was on Twin Peaks at the same time, so we met at an ABC party and we flirted and exchanged numbers -- landlines obviously," Jones told Koenig. "I called him and asked him to come to junior high prom with me. And then for whatever reason -- I don't remember this, he reminded me of this a few years ago -- I called him back and said, 'I'm so sorry. You can't come with me because Al B. Sure is actually coming with me.'"

Reps for Jones and Koenig did not respond to Billboard's requests for comment by press time.

This is the first child for both Jones and Koenig. Jones was previously engaged to producer Mark Ronson but the couple never married.
