'Whitney WAS being discussed as a mentor': Simon Cowell reveals tragic singer was being considered for new X Factor series – with meetings due to start tomorrow

Simon Cowell today paid tribute to Whitney Houston and said the warning signs that she 'still had problems' came after the singer made an erratic appearance on The X Factor in 2009.

Despite battling her personal demons, the Syco boss, 52, did reveal she was to be considered for a mentor role on the US version of the reality show – with discussion meetings to commence tomorrow.

He also alluded to iconic stars Michael Jackson and Amy Winehouse, saying the tragic passing of Whitney was simply 'horrible'.

Simon told Sky: 'There are always moments in your life that are horrible to remember. The day John Lennon died, the day Elvis died.

'More
recently Michael Jackson, last year Amy Winehouse and now Whitney. I
know quite a few people who had been working with her over the years. We
all knew Whitney had issues.

'I
last met her when she came on the X Factor. You could see at the time
there were still a few problems but she was a delight to work with on
the day.

'She probably
wasn’t all together but it was still Whitney Houston and you were in the
presence of a legend and I will never forget that day.

'Whitney was a true diva, but I use that in the nicest possible way. She had one of the best voices I heard in my life ever.'

The
guest appearance on X Factor was billed as the start of her comeback
but the worrying performance included an embarrassing wardrobe
malfunction and raised concerns for her well-being.

In a separate interview with former Britain's Got Talent co-judge Piers Morgan, Simon told CNN: 'We were ironically going to meet on Monday and of course one of the names we were going to be talking about in that meeting as a possible mentor on the new series of X Factor was going to be Whitney.

'Given the choice, I would have liked to have taken her under my wing as well, because she would have been the ultimate, ultimate mentor to any contestant coming on the show.'

He added: 'Ever since doing this job,
particularly doing talent shows over the last 10 years, the No1 singer
anyone ever wanted to emulate, if they really wanted to be a superstar,
was always Whitney.
