Titanic actor Billy Zane has split from his fiancée, People.com reports.

Zane, 42, and British actress Kelly Brook, 28, parted ways last month, according to a report in the U.K.’s Sun.

“The decision was made after long conversations here and in the U.S.,” a source told the paper. “They remain good friends.” They were due to wed at their 600-year-old English farmhouse next year.”

Reporters became suspicious of a split after she appeared at a TV award show last Sunday without her engagement ring.

“Yes, they have split,” Brook’s rep confirmed. “That’s all we want to say at the moment.”

Zane and Brook — who rose to prominence in Britain by hosting a zany morning TV show — met on location in 2004 while filming castaway thriller Three.
