It is not everyday that you hear a beautiful blonde celebrity admit they feel like a “blob” as the penchant for stick-skinny seems unlikely to abate in Hollywood.

However, that is exactly how Jessica Simpson described herself in a recent conference call with US Weekly, in which she was discussing her appearance on reality TV show Fashion Star, which premieres stateside on March 13th.

Still, her reasons for feeling huge are obviously understandable as the 31-year-old performer is on the verge of giving birth to her first child with fiancé Eric Johnson.

Simpson told US Weekly: “I wasn’t pregnant when we shot it [Fashion Star]. It will be amazing to see myself with a waistline.

“I’ll be like a big blob sitting on the couch watching myself thin.”

The singer was pictured by the Daily Mail out and about with her beau in Los Angeles yesterday (February 23rd), where she was snapped exhibiting her protruding tummy.

Nevertheless, she managed to carry it off, looking like an attractive mother-to-be in a full-length maxi dress that paid tribute to the current trend for tribal patterns.

The star, who used to be married to 98 Degrees singer Nick Lacey, complemented the outfit with an oversized grey cardigan, large yellow handbag, big sunglasses and a silver necklace.

Clutching Johnson’s hand in her own, Jessica could hardly have looked happier and appeared to take no heed of photographers’ flashes.

Perhaps her husband-to-be was a little more cautious though, as he gripped Jessica’s hand and in one image glanced at her in what appeared to be a protective manner.

Musician Johnson took a particularly casual approach to the outing as he simply sported grey joggers, white trainers, a grey drawstring hoodie and a burgundy tee.

On Twitter recently, Simpson voiced her passion for vampires when she revealed one of her favourite TV shows.

She said: “Vampire Diaries has been a minor obsession of mine this month!! I’ve watched every episode!! Ok, so maybe it isn’t a minor obsession.. Ha.” [sic]
