Media mogul Simon Cowell has finally admitted that being “Charlie” for three female judges, Demi Lovato and two new judges is not as easy as he thought it would be. Now the three ladies have pulled a prank on him and they made the powerful ‘X-Factor’ judge ate bulls’ testicles.

"They made me eat bull's balls and then Paulina ate them,' Simon said in a video teaser used for next season, according to EntertainmentWise.com. The judges were asked in the teaser of any pranks that were pulled during auditions.

Paulina also shared her side of story on how pranks were played on her at the X-Factor auditions across America.

"I didn't swallow them!" Paulina quipped, adding, "He wanted me to swallow them. I didn't."

The veteran judge noted, however, that he finds the company of the female judges very amusing, as he failed to hide enjoying working with them to The Wrap at the recent conference held this week.

SiCo as he fondly called by media, revealed that he had looked forward to work with Paulina and Kelly for X-Factor USA.

He said, “I’ve wanted to work with Paulina for years and Kelly did the UK show for me and did a brilliant job."

It will be recalled that SiCo had asked Latina Singer and popular pop icon Demi Lovato to return to Season 3 of the X-Factor. Simon says, having the three female judges together on one panel could never be any better.

“It was a very easy decision to put these three together and you hope it’s going to work and they’re going to get on well. And luckily they did,” Simon was quoted as saying by EntertainmentWise.com.

Demi also disses on her new fellow judges - - both Paulina and Kelly. Despite reports flying around that the 21-year-old singer is returning to the show with diva attitude, things appear to be running smoothly on the set.

"It means a lot to me to have the support of someone who's a legend," Demi was quoted as saying referring to Paulina.

Paulina, for her part, talked of a great working relationship with Kelly. She said, "We love Kelly and we're bonding so much."

The three female judges found family in each other as they hit Season 3 of ‘X-Factor’ USA 2013.

Paulina noted, "We believe we're sisters and we support each other and [Simon] doesn't like it."
