Tom Cruise's ex-wife Mimi Rogers wishes "the best" for him and Katie Holmes.

The 56-year-old actress - who was married to Mission: Impossible star Tom from 1987 to 1990 - has expressed her sincere feelings of sympathy towards her ex-husband and his third wife Katie over their recent split.

"I wish them both the best. There's not much else to say. I really do, though. I wish them the best," she told Us Weekly.

Speaking at the New York premiere of bittersweet romantic comedy Hope Springs on Monday night, she reflected on what makes a marriage work and the importance of friendship: "I think marriage is hard work no matter what. I think it's about first and foremost being great friends."

Hollywood couple Katie and Tom - who have six-year-old Suri together - split in June after five years together when the former Dawson's Creek star filed for divorce. Katie has since been granted sole custody of their daughter.
