Talulah Riley files for divorce after 18 months

British actress Talulah Riley has filed for divorce from her internet tycoon husband after 18 months of marriage.

The Inception actress exchanged vows with Elon Musk, founder of internet financial service PayPal, in September (10) after two years of dating.

She admitted at the time that he was the only man she had ever slept with and that her father was against their romance because he thought Musk was a "playboy".

Now the couple has split, and Talulah Riley filed papers to begin divorce proceedings on 17 January (12), citing "irreconcilable differences".

Elon Musk, who announced their break-up on a day after Talulah Riley started proceedings, is yet to file his own papers.
