“Chicago” co-star Renee Zellweger was dining with a girlfriend at Moonshadow’s in Malibu when who should walk in but the man she once claimed was the love of her life: Jim Carrey. What’s more, Jim and his agent were led to a table just a few feet from Renee! Jim smiled, but Renee — who dumped the funnyman — looked like she wanted to crawl under the table!! Finally, Renee quit trying to act cool, hailed a waiter — and got moved to a table far, far away.
