Cowell seemed pleased that a group had finally won the show, tweeting after the final: "Congratulations to Little Mix. And Paula as you can see, groups can win this show! I was really hoping a group would win this year. @OfficialTulisa has done a great job. These girls could be stars."
Now, according to The Sun, Simon is already making plans to turn Little Mix into the next Spice Girls, with reports suggesting they could pocket a cool £8million from commercial deals.
It is thought Perrie, Jesy, Leigh-Anne and Jade are seen as "a marketer's dream" and already have a few offers on the table.
Speaking after their win, Leigh-Anne revealed she knew they could make X Factor history and become the first group to win the ITV programme, stating: "Ever since we went to Perrie Edwards's house and we were rehearsing, I just saw something in us. I knew there was something special and we're here, we've done it, we've won."
Jade agreed: "I knew there was something special [about us]. The minute we started singing together I just knew that something was right about it and it was just a case of getting everybody else to believe it as well."
Tulisa Contostavlos, who steered the girls to victory, went on to claim that despite being not qualified to manage Little Mix, she will continue to mentor her act.
The N-Dubz star admitted on spin-off show Xtra Factor: "I would manage them if I was allowed to, but I guess that's not how it works. I'm a mentor and I'm still going to be their mentor.
Contostavlos added: "I'm always going to be there for them, I will get involved as much as I can, as much as the label want me to be involved with them. I'm just gonna go with the flow and give them as much advice and help as I physically can."
Tulisa is also expected to double her salary on next year's series of The X Factor since winning with Little Mix, with a source telling The Sun she will earn "just shy of a million", adding: "She's stuck by Louis and learnt a few tricks of the trade from him."
"Plus, she sticks to her views. Weaker people might have retracted what she said about Misha B hassling Little Mix to keep things upbeat but she didn't. The producers love her."
Congratulations to both Tulisa and Little Mix!
