The sexy cousin of BB superbitch Grace Adams Short has vowed to become the “Miss Nasty” of this summer’s show.

Shapely blonde Shelley Short has made it to the shortlist for Big Brother 9.

And she has already told producers she will provide even more entertainment than her back-stabbing relative.

The 25-year-old model auditioned for BB bosses last November and they seized on the fact she is related to an infamous former contestant.

When Grace, 22, appeared on BB7 two years ago she was branded the series’ biggest bitch, with fans chanting “Get Grace Out” on eviction nights.

Now Shelley – a former Daily Star Bikini Babe who recently had a boob job to make her a curvy 32E – wants to follow in her footsteps.

Show chiefs were bowled over by her character, looks and person-ality. She has done all the BB workshops and passed police checks.

Now Shelley has been told that although she has not made the initial line-up, she is being kept on standby and could go in the house later – like Amy Alexander, 21, and Jonty Stern, 36, last summer.

When the Daily Star contacted her home in Essex, she said:“I can’t talk.

I am not allowed to or I will get into trouble.”

But a pal told us: “Shelley told the producers that if they thought Grace was a bitch then they’d seen nothing yet.”

The contestants who are being lined up for the new series have all been taken to France.

They will fly back to the UK just in time for the show’s launch on Thursday June 5. The C4 opener will start at 9pm.
