Ty Dolla $ign helped his girlfriend Zalia celebrate her 30th birthday at the Sugar Factory San Diego over the weekend. (The popular spot re-opened last month following the state’s COVID-19 lockdown.)

We hear the couple and their seven friends arrived around 8 p.m. where they first hit The Theatre Box — the hot spot’s movie theater — for a private viewing of a video message for the birthday girl from family and friends.

They then moved to the restaurant area where the crew enjoyed rainbow sliders, salmon salad, and fettuccine alfredo for dinner — and a massive, 24-scoop King Kong Sundae for dessert.

Ty, 35, and Zalia “were holding hands and acting affectionate,” an insider told Page Six.

The party continued until around midnight when the couple made their way out — but not before stopping into Sugar Factory’s retail store for some road candy.

A rep for the restaurant told us the eatery “followed all city and state guidelines put in place by the CDC and leading health professionals to maintain a safe and healthy environment in our restaurants for our guests and staff.”

The couple has been dating for some time now, going Instagram official in January.

The “Or Nah” rapper previously dated Fifth Harmony singer Lauren Jauregui, reportedly splitting with her in April 2019.
