Donna Air loves mac and cheese.

The 35-year-old star is obsessed with the calorific meal and enjoys nothing more than to sit down to a portion of the American classic with James Middleton.

The blonde beauty was seen rushing off from a swanky bash at the W Hotel London in Leicester Square last night (07.10.14), - also attended by Radio 1 DJ Rob Da Bank and 'Fast & Furious 6' actress Clara Paget - in favour of returning home for a hot plate of her favourite treat with the 27 year old.

While the 'Splash!' contestant has been dating the Duchess of Cambridge's brother, James, for almost two years, the entrepreneur still seems keen to woo his beloved, and promised to whip up the carbohydrate-packed dish for her on Tuesday evening in a bid to show off his culinary prowess.

Before heading home, the fashionable star, who unveiled her 'Little Bird' jewellery range earlier this year, also hinted that she has plans to begin creating one-off items.

The 'Mummy Returns' actress was overheard gushing about her collection at the event, claiming to have received requests for bespoke pieces from several of her celebrity mates.
