Just days after Anstead finalised his divorce from "Flip & Flop" host Christina Haack, from whom he split in September (20), he is said to have already moved on - and he's snagged an Oscar winner.
According to TMZ, Anstead met Zellweger earlier this month (Jun21) after teaming up to shoot an episode of his new Discovery+ show "Celebrity IOU Joyride". They hit it off, and have since started dating.
"Celebrity IOU Joyride" features Anstead and his co-host Cristy Lee helping stars surprise a loved one with a unique car transformation.
Representatives for the rumoured new couple have yet to comment on the romance news.
Zellweger was last linked to musician Doyle Bramhall II, and used to be married to country superstar Kenny Chesney until their split in 2005.
Meanwhile, Anstead and Haack were married for less than two years before separating. They share custody of one-year-old son Hudson while Anstead also has two kids from a previous relationship.
Renee Zellweger once dated Jim Carrey as well. They first met on the set of 1999's film "Me, Myself & Irene". Director Bobby Farrelly claimed Carrey "flipped for her immediately."
In his book, "Memoirs and Misinformation", Carrey even called the actress "his last great love." He later said in an interview, "I don't regret, I don't have those things, but I do appreciate the people that have come through my life for the good that they gave me."
