Jessica Simpson confirms she is pregnant.

Jessica Simpson finally confirms she is pregnant, making an official announcement on her website.

Jessica Simpson, 31, wrote a short message, telling her fans: “It’s true, I am going to be a mummy.”

The reality star and former singer, who is engaged to NBA star Eric Johnson, also comically dressed up in a mummy Halloween outfit in a photograph to accompany the announcement, while cradling her bump.

Jessica Simpson has been at the centre of swirling pregnancy rumours for weeks now – but until today has remained mum.

According to a Boston-based gynaecologist, Jessica Simpson is at least six months gone and is heading into her third trimester.

Dr. Dave David, told RadarOnline: “She looks to be 26 weeks, which is around six months.

“It is definitely a pregnancy and not weight gain. You can by the shape of her abdomen, her belly wouldn’t be that rounded if it was just fat.”

On Monday, Jessica Simpson reunited with Eric Johnson after jetting back to the West Coast from her business trip in New York.

Jessica Simpson was seen laying a protective hand over her growing tummy as she walked hand-in-hand with her fiance.

The former singer was dressed casually in black leggings, platform Alaia boots and a holey beige jumper.

Eric Johnson was the perfect gent and helped his wife-to-be into their black BMW by holding the door open for her as she got in.

Jessica Simpson and Eric Johnson looked in good spirits as they put on a smiley display during their outing in Beverly Hills.

Last week Jessica Simpson, along with her mother Tina and some friends, checked out several apartments in New York.

Jessica Simpson is reportedly looking for somewhere to buy in New York City for her and fiance Eric Johnson to reside now that she spends so much time there working on her fashion lines.
