Asked which X Factor judge's line-up impressed her most, Solomon replied: "Definitely Tulisa - her acts are really strong.
"Ella Henderson is my favourite in the competition this year but I also really love Jade Ellis – her look is awesome and she has a lovely tone to her voice."
Solomon also ruled out the idea of appearing on The X Factor's rival reality show Strictly Come Dancing.
"I'm a terrible dancer," she confessed. "And I couldn't see myself improving in any way, shape or form. Dancing is not in our family, dad has two left feet and I'm no better."
Solomon was speaking after helping break a Guinness World Record by placing the 250,000th brick onto a giant Ben 10 'Bloxx' alien sculpture in London today (October 10).
The three-metre-high, one-ton structure was constructed during a tour of ten UK cities, winning the record for the most participants to build an interlocking plastic brick structure.
It has been created to promote the forthcoming series of Ben 10 Omniverse, premiering on Cartoon Network on October 6.
