So that's her Victoria's Secret! Jamie Lee Curtis, 56, makes a busty display on Scream Queens while wearing bra championed by Kylie Jenner

She caused much gasping around America during her recent eye-popping appearance on Scream Queens.

And it has emerged a special bust-boosting bra championed by none other than Kylie Jenner was the secret behind Jamie Lee Curtis' boldly up-front display this week.

While it is not the first time she has used her ample assets to excite her legion of fans, it was the Victoria's Secret Bombshell bra, which Kylie makes her chest appear two cup sizes bigger, that made her look so fantastically firm at 56.

But it was not just the people at home who got a cheap thrill out of the Trading Places favourite's appearance, where her university dean character tried to bed a parent, for everyone on the set of the Fox show was just as excited

A source told Us Weekly: 'When Jamie Lee Curtis was trying to seduce Oliver Hudson on the show… the whole cast was screaming and hollering because of how hot she looked. 

'Jamie shimmied around for everyone and is such a great sport.'

Jamie has hardly been shy about flaunting her knockout body in the past however.

For in addition to noteworthy topless appearances in the likes of classic 1983 Eddie Murphy comedy Trading Places, she  also won much admiration for her semi-naked dancing scene in 1994 action hit True Lies.

She strutted her stuff in just a skimpy bra and panties for Arnold Schwarzenegger in a darkened room, her character Helen not realising the man she is dancing for is actually her secret agent husband Harry, who he set up to believe she was taking part in a top secret mission in a bid to spice up their marriage.

Meanwhile the A-list actress, who is the daughter of Hollywood icons Tony Curtis and Janet Leigh, has also proved to be a boon in inspiring her fellow castmates in the horror-comedy show. 

The insider said: 'Jamie Lee is incredible… the things she comes up with (on the fly) sometimes are better than what anyone would have written. She also kind of keeps the young girls in line.

'Emma (Roberts), Lea (Michele) in particular really look up to her and are on their best behavior in front of her. They want her to like them so they are really good and sweet around her.'
