The X Factor judge has now responded to the offer, expressing interest in dating the rapper.
"50’s someone I grew up listening to. He’s a big star in my eyes so it was definitely very complimentary," she told Bliss magazine. "I’d definitely do dinner with him."
50 Cent made the offer in July 2012, speaking of his admiration for Tulisa and her handling of the sex tape leak earlier in 2012.
"I'm going to be over in the UK later on again in the year and I would love to meet Tulisa for dinner," he said in July of this year. "She had it tough and she has also been through some s**t recently as well."
"I love how she has handled that by flipping the bird to that guy who sold her out."
Tulisa successfuly won her legal case against ex-boyfriend Justin Edwards after he leaked a video of the pair engaged in a sex act backstage at an N-Dubz gig.
