Leonardo DiCaprio is a real family man when it comes to that Vittoria Ceretti … because Leo went out to eat with his chick's parents and siblings.
The actor and his model girlfriend met for a family dinner in Los Angeles on Thursday night at Anajak Thai Cuisine in Sherman Oaks.
Leo was dressed in all black with his signature ball cap and face covering… keeping a low profile before the family gathering.
Vittoria looked stunning as always. She arrived separately from Leo and also left at different times.
We've seen Leo and Vittoria go on quite a few family trips this year, but usually just grab a bite to eat with her parents … and now Vittoria's siblings are joining them.
Check out the gallery…it looks like everyone had a good time.
By the way, something tells us that Leo picked up the check.
