Jennifer Aniston's rep denies twin pregnancy rumours

Jennifer Aniston's representative has shot down new rumours the actress is expecting twins.

The former Friends star has faced persistent speculation she is pregnant since she began dating Justin Theroux last year.

A new round of reports started after she confirmed her engagement to the actor in August, and editors at a U.S. tabloid magazine suggested earlier this week that the actress is carrying twins.

Aniston's publicist insists the latest story is false, telling GossipCop.com, "She is not pregnant and shame on them for once again making up the whole story."
