Carey Mulligan and Marcus Mumford might have only been together for five months, but their relationship's moving at record speed if reports of an engagement are to be believed. Exciting!

The Mumford & Sons singer reportedly asked Carey to marry him during their stay at Babington House in Somerset this weekend, the Sun reports.

Carey couldn't contain her excitement and was apparently happy for her fellow guests at the posh hotel to see her diamond ring. A source said: "They were stuck to each other like glue."

The couple met when Marcus performed in Nashville, Tennessee earlier this year, and have been getting ever more serious as the year has progressed.

Carey played the field after splitting from Shia LeBeouf last year, briefly dating Tom Sturridge and Eddie Redmayne, while Marcus was previously in a relationship with singer Laura Marling.

There's no official word from their reps yet, but we're already picking out a hat...
