The celebrity wedding train continues to pick up passengers and the latest to board is British singer Lily Allen.
The couple was on holiday in Bali when Cooper popped the question and they celebrated in their hotel bar, sharing their story and drinking champagne with other guests.
Allen marked the occasion with an understated Twitter post: "Happy holidays everyone, xxxx."
Allen's engagement comes at the end of a hard year. In November, she suffered a miscarriage six months into her pregnancy. It was her second miscarriage in the last two-and-a-half years. On the heels of that incident, she was diagnosed with septicaemia, a life-threatening blood disorder.
