Malaika Arora Khan and husband Arbaaz Khan [Images] are reportedly heading for a divorce.

The news came as a surprise to many, who considered their 10-year marriage to be quite solid. The couple has a son, Arhaan.

Reasons for the split are not know yet.

After his acting debut in Daraar, Arbaaz's career did not take off. He has been seen since in small roles, the latest being Apoorva Lakia's Shootout At Lokhandwala [Images].

Malaika, on the other hand, has become quite successful post her sizzling item numbers, from Dil Se's Chaiya Chaiya to Welcome's Hoth Rasiley.

When a television channel, Live India, asked the couple about the divorce, Arbaaz and Malaika neither confirmed nor refuted the news.

"It was my private life and I would not like to discuss it in public," Arbaaz told Live India, adding, "Life is uncertain and no one knows what will happen tomorrow."

Malaika seemed to be shaken when she spoke to the channel. "It is too personal and I would like to keep quiet on this issue," she said.

When reminded that keeping quiet on such issues indicates trouble, Malaika said, "I believe silence is golden."

The news comes as a surprise especially at a time when Malaika and Arbaaz are getting ready for their Kannada film together, Shaadi Ke Side Effects. The film, which is about marriage and infidelity, sees Malaika in her first lead role. One wonders if the news of the divorce at this time is a kind of promotion for their film.
