The singer has been gushing about her new romance with the American dancer, saying it's 'intense' and 'genuine'.
She told fans at the event: "There's an intensity, there's a trust, there's a love - a genuine love."
She added: "He is very experienced in what he is doing. He is a ridiculously talented character."
Cheryl went public with Tre earlier this year and reports suggest that the couple have spent as little as three days apart since.
The Girls Aloud star looked super stylish at Saturday's event at London's Corintha hotel, in a gold and orange silk dress with a split that gave a glimpse of her toned midriff.
Cheryl was just back from a whistle stop trip to LA where she paid a not-so-secret visit to Simon Cowell's house, prompting rumours she is in talks to return to 'The X Factor' next year.
