The Oscar winner, 48, was said to have accepted the Prometheus star's proposal over the Christmas (12) holidays, having dated on and off since 2008. However, a spokesperson for Tomei insists there is "no truth" to the wedding rumours, reports GossipCop.com. The Wrestler actress, who has previously been romantically linked to Robert Downey, Jr. and Lenny Kravitz, has previously claimed she did not believe in marriage, saying, "I'm not that big a fan of marriage as an institution and I don't know why women need to have children to be seen as complete human beings."
