Slow news day alert. Jennifer Lawrence is larking about London at the moment. Here she is with Tom Ford after they had dinner together at Firehouse. It's OK - Jennifer's fella Nicholas Hoult was also present. That and we doubt Jlaw's Tom's bag for obvious reasons...
As you can see, she just happens to be wearing an arbitrary ring on her ring finger - so now she's obviously engaged. According to heatworld, there's no other viable explanation...
Like we said, slow news day.
