Happy birthday, Tori Spelling

The actress turned 45 on Wednesday and celebrated with a sweet family dinner at Innovative Dining Group’s Katana West Hollywood. 

A source tells ET that family -- sans Spelling and husband Dean McDermott's youngest child, 1-year-old Beau -- arrived at the restaurant with big smiles at around 7:30 p.m., and enjoyed eats like popcorn shrimp tempura, Chilean sea bass and white lotus sushi. 

The source says Spelling and McDermott seemed happier than ever, but focused on their four kids: 11-year-old Liam, 9-year-old Stella, 6-year-old Hattie and 5-year-old Finn. 

Spelling took to Instagram to share a few snaps from the night's festivities. "Best birthday dinner with my family at @katanarobata Love the sushi and robata bar so much! Thx @shaesavin for everything! Xoxo," she captioned the slideshow. 

The actress also spent her birthday with her former Beverly Hills, 90210 co-star, Jennie Garth. "Loved spending my bday with my bestie for life @jenniegarth My rock, my sister, my bff xoxo," Spelling wrote alongside a sweet selfie.
