Justin Theroux is said to be annoyed after Jennifer Aniston invited her father and his second wife to move in with them.
The pair have only recently finished renovating their $21million mansion in Bel Air, Los Angeles, and Justin is said to be annoyed after his fiancée invited her father, John, 80 and his second wife, Sherry, 57, to live with them.
A source said: ''Justin is steaming mad over Jen's offer. He told her that having her dad ambling about the house is a huge 'buzz kill'. He worries it's going to destroy their love life before they've even tied the knot.
''Justin tried to plead his case, but Jennifer told him she's made up her mind. She said he has no right to even question her because of how much time he's been away.''
Justin, 42, has spent a lot of time on the other side of the country recently, filming in New York, although he is said to have made it back for Thanksgiving, but he is still worried her father - a veteran soap actor - will try to interfere with their personal affairs.
The source added to the National Enquirer magazine ''John is already pestering him about when he's going to have marry Jen and give him a grandchild.''
John and Sherry are said to have recently put their house on the market and were having trouble finding something suitable to move to when Jennifer stepped in to offer them a place to stay.
