Willis 'to marry Emma Hemming'

Bruce Willis and Emma Hemming have been shopping for an engagement ring, say reports.

The Hollywood actor, 53, was spotted at the Cartier ring shop in Beverly Hills, claims Life & Style.

"Emma seemed to like one that had a very art deco feel to it," said a source. "It was a smaller diamond set in platinum, and it was very feminine and unique."

Willis was married to Demi Moore between 1987 and 2000 and was briefly engaged to Brooke Burns in 2004. He has three daughters from his first marriage, Rumer, Scout and Tallulah.
