Lovebirds Jennifer Lawrence and Nicholas Hoult enjoyed a romantic day in London Thursday, holding hands for a walk as the busy actors take a breather from their fast-paced careers.

After enjoying a lunch at an outdoor cafe, the couple, who are costars in the X-Men franchise, set off on foot. They were bundled up a bit for their outing in the spring chill, with Lawrence, 23, sporting a black leather jacket, a burgundy fedora and a large turquoise ring on her left hand.

A rep for Lawrence says it’s not an engagement ring.

They later gussied up to join newly married fashion designer Tom Ford, 52, for dinner Thursday night at The Chilton Firehouse restaurant and bar, with Lawrence stepping out in a black jumpsuit covered with a camel coat, her sleek bob slicked back and away from her face.

While free time is often rare, Hoult, 24, told the spring issue of V magazine, released in March, that working together with his girlfriend on the latest sequel, X-Men: Days of Future Past, was an added bonus.

“It’s fun because in this business you are away from one another for long periods of time,” he said, “so when you’re on set together it’s a brilliant thing, because you actually get to spend time together.”
