(Cover) - EN Showbiz - Justin Theroux probably finds the interest in his romance with Jennifer Aniston "odd", says his cousin.

The Hollywood actress met Justin while they were shooting the film Wanderlust together and they have been an item for around a year, with speculation they are preparing to get engaged.

Justin's cousin Louis Theroux can't begin to imagine the effect all the romance rumours must be having on his relative.

"She's used to it, she's been world famous for a good 15 years. This is a different thing for him. He wasn't massively famous not like now," Louis told British magazine Grazia. "They live in LA so I don't know a great deal about their lives, but I think it must be quite odd for him."

Louis is an investigative journalist who is famed for his documentaries in the UK.

He is happy Justin has found the love of his life. "The heart wants what it wants, so I think it would be a bit mean of me to begrudge the happiness that he has found," Louis added. (C) Cover Media
