The former N-Dubz singer told Yahoo! omg! that she's loving the style of the girl band - and gets inspiration from their looks.
And there's one Mixer in particular that she's fashion crushing on.
Speaking to us exclusively ahead of her performance at Vodafone's London Fashion Weekend last night she said: "[Little Mix] are cool. I'm loving their fashion at the minute.
"I keep seeing Jade in these little outfits and being like 'I wanna rock that'. It's fun. I'm 24 and I still have plenty of days when I dress like I'm 18."
Tulisa, who hit the stage at Somerset House last night to perform five tracks in a white lace puffball dress in amongst an uber glam fashion show, told us her own personal style has got a lot more girly since she traded in N-Dubz for X Factor.
She told us: "X Factor is the time and place for glam. It's amazing dressing up in these beautiful dresses that I would never have been able to do with N-Dubz because it just wouldn't have looked right. I wouldn't have fit in with the lads.
"I've definitely got girlier. I've got two complete sides. Sometimes I'm a bit of a tomboy and dress like one and other times I'm really girly. I go through mood swings."
Asked whether she minded that she was dubbed Vicky Pollard when she donned her "tomboy" pink tracksuit earlier this month she said: "That was my mate. My best mate. It wasn't a random person, it got mis-reported.
"When I'm not working I sit in a tracksuit for comfort. My feet are in agony from all the heels I wear."
And she told us that her new fashion range 'Live It Up' for Bank is going to be full of fun.
Asked whether it'll be full of cheekiness and flesh on show she said: "Definitely. It's everything from a bit of casual wear to real dress up, to more sexy outfits for performing.
"Because my fashion is a bit rebellious at times it was hard for the fans to know how to reenact it. So I thought why not do my own collection."
