Jason later replied: “Hey BFF this was so much fun. Thanks for having me. Love you.”
And her fans were quick to notice the giant rock glinting away on her ring finger.
“It’ll be a great episode! (Curious about the wedding ring?)” one fan wrote.
“But who gave you the ring?” another person stated.
A third person added: “That ring is a beast!”
Anna, who is engaged to cinematographer Michael Barrett, hasn’t been too vocal about her engagement and is rarely captured wearing the dazzling gem-stoned ring.
However her Mom costar Allison Janney previously confirmed the happy news. The actress told Us magazine in mid-January that the two have “been engaged for a long time.”
The pair began dating in 2017 after working on Faris’ film Overboard and were spotted together for the first time in September 2017.
Despite being caught wearing the ring on Monday, it’s not the first time the Mom star has been photographed up close with the ring on her finger.
Fans were seemingly dazzled by the rock, when she recently wore it on while appearing as a guest on the Kelly Clarkson Show.
Anna was preciously married to actor Chris Pratt. The couple split in August 2017 and share seven-year-old son, Jack. Chris is now married to Katherine Schwarzenegger.
