They've been engaged for three years, and had a suspiciously wedding-like party last night

Crack out the champagne and get your glad-rags on, because if reports are to believed Jennifer Aniston is a married woman again.

The Friends star, 46, has been engaged to Justin Theroux, 44, for three years, but in a new twist to their romance – which has been plagued with are-they-aren’t-they-rumours in the past – it looks like the pair might have tied the knot.

‘The couple exchanged vows in front of more than 70 family members and friends on Wednesday at their Bel Air home,’ sources confirm to PEOPLE.

The next morning the pair were snapped boarding a private jet heading off for what’s been reported as their honeymoon.

In new pictures published by US gossip site TMZ, their garden looks decidedly…well, like a wedding reception. White-clothed tables are laid out in their very spacious yard, along with a marquee and some decking that’s suspiciously aisle-shaped.

The pictures, which appear to have been taken from an aircraft, also show various comings and goings into the house. In one, a man wearing a very vicar-like dog collar appears to be striding in, Bible under his arm, and in another, a cake with two cartoon figures on top is carried into the house.

So, all sounds like a wedding, doesn’t it! According to TMZ, though, it was just your run-of-the-mill birthday party.

Their source said Jen was simply throwing Justin a big bash for his 44th birthday. So, if Justin is into birthday parties that are organised like weddings and look a lot like weddings, then he was in luck.

This isn’t the first time Jennifer and Justin have been subject to such a rumour. Earlier this year, in an interview with InStyle, Jen hinted that she would have a secret wedding, saying: ‘Do you just do it and say screw it? Or do you try desperately to get away with [doing it secretly]? …If we could do it without all the buzzing and the noise…It can be done. When there’s a will, there’s a way.’

Last month, some American sites reported that the pair had married in secret, with some even saying that the wedding happened earlier this year. This are the strongest reports to date but there has been no official statement from either Justin or Jennifer’s reps.  If it is true, we’re shouting ‘congrats’ to this gorgeous two-some from the hilltops.
