Love is about to have a whole new meaning for Paul Rust and Lesley Arfin.

The Netflix show’s co-creators were spotted at Canter’s Deli in L.A. in April at a launch party for Haim’s new album, with Arfin sporting a noticeable baby bump, an onlooker tells PEOPLE.

“Rust was very attentive to her and she was his No. 1 priority,” the onlooker says of the mom-to-be, who was spotted sipping on water and mingling with Jennifer Meyer while other event-goers enjoyed SVEDKA cocktails.

The two officially announced the pregnancy on Mother’s Day, sharing Instagram posts captioned, “She’s having a bb” and “Happy (second trimester) Mother’s Day.”
