Billie Piper and her ex-husband Chris Evans have crossed paths at the star-studded premiere of Rare Beasts.

The former Doctor Who star, 37, arrived at the Curzon Mayfair cinema in London wearing a lacy black dress that featured circular decorative panels and a swirling pattern.

The Olivier Award-winning stage actress tied her blonde hair back and complemented the outfit with black high heels, pink lipstick and silver earrings.

They divorced in 2007 but remain close friends.
