Ant Anstead and girlfriend Renée Zellweger are still wheeling and dealing - and completely smitten - after five years of dating. "How it started ....." Anstead, 47, wrote in a rare Instagram tribute to Zellweger, 56, on Friday, April 24, in honor of their anniversary, sharing a throwback photo from what appeared to be their meet-cute on Celebrity IOU Joyride. "Happy FIVE YEAR anniversary my beautiful lady!" he gushed. "Hands down The best human I know! Luckiest boy! I love you my Ren 💫❤️ x." In the photo, Anstead looked lovingly at Zellweger as she laughed while holding a power tool.
