Jennifer Aniston denies Justin Theroux marriage rumours

Jennifer Aniston has laughed off reports that she is engaged.

The Horrible Bosses star shot down reports that she is getting married to boyfriend Justin Theroux.

"Rumour number one - I am not planning to get married any time soon," Aniston told Hello.

"I've been married once, and I don't know if I'll get married again. But I can tell you that as of this very moment, I have no plan to get married. Got that?"

The actress went on to deny claims that she is expecting a child.

"And rumour number two - no, we're not pregnant," she said. "It's just I quit smoking, so I've gained a couple of pounds."

Aniston previously insisted that she is in no rush to start a family, saying she believes that it should happen when the time is right.

In August, she reportedly couldn't stop talking about having children with Theroux, who she has been dating since May.
