Actress Vivica A. Fox has dismissed rumours suggesting she has started dating her Chocolate City co-star and onscreen son Robert Ri'chard, insisting she is "very happily single".

Reports surfaced online this week (begs01Dec14), suggesting the 50-year-old Kill Bill star had struck up a romance with Ri'chard, 31, after working together on the forthcoming strip club drama.

Their co-star Darrin Henson was even said to have confirmed the budding relationship and was quoted as allegedly stating about Fox and Ri'chard's age difference, "Age is nothing but a number".

However, Henson has since taken to Twitter.com to deny ever commenting on the romance rumours, writing, "let's make it clear I never asked ri'chard anything because I saw and knew nothing about it (alleged relationship) til just now (sic)".

Fox has also set the record straight and in a tweet to fans, she writes, "Well let the ChocolateCity rumor drama begin! I'm very happily single n not dating Anyone! Fact (sic)".

The veteran star previously dated rapper 50 Cent and was engaged to club promoter Omar 'Slim' White until their split in 2011.
