Bob Saget is filling his house again ... he's engaged to his girlfriend, Kelly Rizzo.
The "Full House" star announced the engagement Tuesday in a totally most Saget way. After a double date with Kelly, pals Katie Killean and ex-"Seinfeld" producer George Shapiro -- he captioned this shot, "In case you’re wondering, we were celebrating our engagement — and I know George and I will be very happy together."
Not Bob's first time down the aisle. The 61-year-old was married to Sherri Kramer Saget for 15 years, but they split in 1997.
We know what you're thinking -- Bob digs 38-year-old Kelly for her big ole sense of humor. She showed it off too with her own engagement shot. Mazel!
