But as Jennifer stepped out with friends for dinner in West Hollywood on Tuesday night before issuing the denial, she looked in great spirits.

The We're The Millers actress was seen grinning from ear-to-ear as she left celebrity favourite restaurant Cecconi's following the dinner party.

Layering up, Jennifer looked chic in a brown jacket, scarf and khaki trousers, teamed with beige pointed court shoes.

She was seen flanked by security as she left the eatery, where frequent star diners include Tom Cruise, Simon Cowell and Halle Berry, via the rear exit, clutching a large Burton gift bag as she did so.

After Us Weekly's magazine cover declaring Jennifer's 'pregnancy', a representative for the actress told MailOnline: 'Jennifer is not pregnant.'
