Speaking at yesterday's series nine launch, the two female stars paid tribute to each other and rubbished early rumours of a rift.
"She's lovely and and always so graceful. She's great to work with," said Tulisa about her new co-star.
When asked about a potential fashion rivalry on the Live Shows, the Camden singer commented: "When it comes to fashion. I'm a bit more back to the roots, mixing the street vibe with the glam. I'm still finding myself.
"Nicole found herself a long while ago, she's found her fashion. You can see her coming out looking glam and I'll be trying to find myself."
Scherzinger added: "Tulisa's gorgeous and she just keeps it real. I like to switch it up a lot, so we'll have fun with it."
Louis Walsh joined in the praise for their newest addition to the X Factor panel, describing Scherzinger as a "star and a winner".
"She brings experience. She's been a Pussycat Doll, she won Dancing with the Stars, she's a singer, a dancer, she ticks all the boxes," said the Irish judge.
The X Factor series nine starts on Saturday, August 18 at 8pm on ITV1.
