Former Pussycat Doll singer Nicole joined the panel as a new judge last month, sitting alongside Gary Barlow, Tulisa and Louis Walsh.
Misha, who finished fourth on the show last year, told DigitalSpy this week: "I love Nicole. I actually got the chance to meet her and she was very, very sweet and supportive.
"She's very passionate and you can see she's very genuine. I think she'll add an extra spice [to the UK panel]."
Misha, who was mentored by ex-judge Kelly Rowland last year, added: "She'll add that US flavour and she emotionally connects. She's had the experience she needs to be a judge."
Nicole joined the panel for the final auditions last month and will appear permanently from bootcamp onwards.
