Surprise! Vampire Weekend frontman Ezra Koenig and Rashida Jones are parents, Us Weekly reports. Jones had the couple’s first child, a boy named Isaiah Jones Koenig, on August 22, according to E! News. Congratulations to Rashida and Ezra! (Pitchfork has contacted representatives for Rashida Jones and Ezra Koenig.)

Rumors that Koenig and Jones were dating began in 2016 when they attended a New York Knicks game together. They were then spotted together at the 2017 Sundance Film Festival, seemingly confirming the rumors. They have not publicly acknowledged their relationship status.

Koenig continues to ready Vampire Weekend’s fourth album—the long-awaited follow-up to 2013’s Modern Vampires of the City. This past August, he said that the record is finished and was in the process of mastering. He also played some new songs from his phone at a Chicago show.
