Ciara's ex-fiancé Future claims he doesn't care she is dating Russell Wilson.

The 'I Bet' hitmaker, who has two-year-old son Future Jr. with the rapper, went public with her new romance with the NFL quarterback at the US President Barack Obama's Japanese state dinner at the White House in Washington DC this week.

But her former partner, whose real name is Nayvadius DeMun Wilburn, took to Twitter to hit back at suggestions he was upset about seeing photographs of them together, writing: ''I wish I cared''

The 31-year-old star later added: ''Yall mad as s**t... (sic)''

Ciara and Future split in December after trying to mend their relationship in August following rumours he cheated on her with his stylist while on tour, but she recently insisted they are ''cool.''

A source told E! News that the 29-year-old beauty is now smitten with Seattle Seahawks player Russell, 26.

The insider said: ''It's still at the beginning stages and it's very fresh. She thinks he is a complete gentleman and has really enjoyed hanging out with him these past few weeks. It's constant laughter and fun with them.

''Things are a bit busy for both of them now, but they are willing to make time and see where this may go.''
