Lindsay Shookus left Ben Affleck at home for Hollywood’s big night on Sunday, going solo to a Golden Globe Awards after party.
The Saturday Night Live producer smiled for a picture at show host Seth Meyers’ Golden Globes after party.
Although Affleck sat out the event, he was spotted helping his girlfriend pick out shoes during a casual shopping date in Los Angeles earlier in the weekend. The two were photographed smiling as they shifted through some footwear.

Since publicly stepping out as a couple in July, the duo have moved in together. A source previously told PEOPLE that around October, Shookus moved into a New York City apartment that the Justice League star pays for and stays at when he’s in the Big Apple.

Affleck has also continued to spend time together with ex-wife Jennifer Garner and their kids — Violet, 12, Seraphina, 8 and Samuel, 5. In addition to spending Christmas Day together as a family, the pair were spotted taking a morning stroll together in Los Angeles in December and got together for Thanksgiving as well. The Oscar winner capped off that holiday by taking his daughters to see the hit musical Hamilton.
