The singer is apparently in her first real relationship since splitting from ex-husband Ashley Cole.
The 29-year-old star was pictured with American dancer Tre Holloway leaving a London restaurant.
A told The Sun newspaper: "It`s early days but they are an item."
They met when Tre appeared alongside Cheryl as she performed her single `Promise This` on 2010`s `X Factor` live finals.
Cheryl met up with him again when she celebrated her 29th birthday in Las Vegas, Nevada last month - and the pair have been inseparable ever since.
A source said: "It`s going well. They really like each other."
Cheryl has had a string of secret dates with Tre and has apparently been out with him twice this week alone.
On Monday they enjoyed a double date with Girls Aloud bandmate Kimberley Walsh and her boyfriend Justin Scott at Nobu restaurant in West London.
Then on Tuesday she put on a black mini-skirt and vest top for another meal with him at Roka restaurant in central London.
A fellow diner there said: "They are clearly very close. Several times Cheryl leaned in to him and touched his knee as he spoke. There is certainly a spark between them."
The former `X Factor` judge has never admitted seeing anyone since her divorce from England and Chelsea ace Ashley Cole, 31, in 2010 - although there were rumours about her friendship with dancer Derek Hough.
Cheryl`s new man is believed to be a close friend of her mentor and confidante will.i.am.
Los Angeles-based Tre, who comes from New Jersey, has been a dancer for singer Leona Lewis and also appeared on `American Idol`.
He graduated from university with degrees in finance and psychology.
