The "Bridget Jones's Diary" star was snapped kissing her new man on Laguna Beach, California on Saturday, July 17 and now Ant's close pal and "Wheeler Dealers" co-star, Mike Brewer, says the two are smitten.
"I think Renee has found her Prince Charming and Ant has found a real woman in Renee," he tells Britain's Daily Mail newspaper. "He’s got a woman who cares about him, and he cares about her. They are both wonderful people and they deserve this happiness."
"They just clicked, and the timing was right. They wanted to keep it private at first. When you’re in a new relationship, you don’t know if it will work or not so you’re not sure if you should tell your friends or share it with your family."
"But Renee is comfortable now with them being seen together, shopping at Home Depot (U.S. home supply store) or just doing the ordinary things other couples do."
Renee and Ant met when she guest starred on his show "Celebrity IOU: Joyride" and Mike says she has already started to bond with his son.
Hudson, 22 months, from his second marriage to Christina Haack, host of American property programme "Flip or Flop", and she has even been FaceTiming his teenage children, who live in the UK with his first wife Louise.
"Renee has a great relationship with Hudson, something that's obviously very important to Ant," Mike adds. "Ant's an all-round good guy but one of the nicest things about him is that he's a good dad. He's always on the phone to those kids, even though he can't see them right now. He's such a devoted father he makes the rest of us look bad."
