Jennifer Aniston and Justin Theroux have married in a secret ceremony at their $22m Bel Air mansion.

The couple are understood to have exchanged vows in an intimate A-list ceremony on the grounds of their stunning California estate on Wednesday.

Reps for the pair are yet to confirm the news, but multiple sources say the huge party being thrown was a wedding celebration.

The event comes just days before Theroux's 44th birthday and, fittingly, three years after The Leftovers star proposed on his birthday in 2012.

Photographs being run on TMZ show a cake arriving to the mansion featuring a his and her puppet topper. Also check out people that attended the wedding.
