Are these Avengers stars the next Hollywood power couple?

Only days ago rumours went into overdrive that co-stars Elizabeth Olsen and Tom Hiddleston were a couple.

The pair were spotted lunching together on London and just last night were reunited again for dinner at The Wolseley. Twenty-six-year old Elizabeth and 34-year old Tom starred opposite one another in the play I Saw The Light. They played husband and wife, interesting.

Back in May the pair were seen looking very cosy strolling down the street and accordingly to US Weekly were something of an item even back then.

An insider claimed that the pair were together saying: 'It's casual. But they do make sure to text when they're apart.'

Since Elizabeth called off her engagement to fellow actor Boyd Holbrook in January, there has been plenty of speculation that she and Tom are a couple.

Both are connected to the Marvel Avengers movie series but appear to be spending quite a lot of time together outside of their work commitments.

A source told US Weekly that since calling off her engagement Elizabeth wants to enjoy her newly single status: “She wants to make a new life for herself. She's having fun.”

The very stylish pair have yet to comment on their rumoured relationship but all signs point to a possible new couple as they attempted to hide from photographers leaving dinner this week.

Also of note, the duo were out by themselves. So those ‘dinner with friends’ excuses might be a little hard to sell after this one.
