(Cover) - EN Showbiz - Simon Cowell has turned "nice".

The American X Factor judge, who is renowned for his brutal honesty and ruthless business decisions, is said to have become more gentle after receiving advice from his fellow X Factor mentors Nicole Scherzinger and Paula Abdul.

The 51-year-old has reportedly been taught about positive energy and the calming influences of Asian cultures by the two stars.

"Backstage Nicole and Paula have been giving Simon pep talks focusing on positive energy. A couple of bemused colleagues have since overheard him talking about being more zen' and having good energy'," a source told British newspaper The Mirror. "Those who have had a glimpse of Tuesday's first preview advert for the show are shocked by the new and unusually gentle side to Simon's judging. It's all a bit strange."

Simon came under intense scrutiny earlier this year when long-term friend and protg Cheryl Cole was sacked from the American version of the popular show, after he had orchestrated her move from the UK X Factor to join him as a judge stateside. (C) Cover Media
