Ricky Hil was arrested on Saturday evening (17.10.15) after allegedly punching a bouncer outside a nightclub.
The 25-year-old rapper - who dated British pop star Rita Ora until their split in July this year - is said to have been involved in a physical altercation after his friend was told that his clothing didn't match the dress code of the LIV nightclub in Miami Beach.
Ricky - who's the son of fashion designer Tommy Hilfiger - has been charged with battery and disorderly conduct, as well as possession of less than 20 grams of marijuana, according to the New York Post newspaper.
Ricky was released by the police at the Turner Guilford Knight Correctional Center on the same night the incident is alleged to have occurred.
The rapper's one-year relationship with Rita - who is combining her music career with acting as a judge on the 'The X Factor' - ended earlier this year when the pair decided that their hectic working schedules made their romance impossible to sustain.
A source previously said: "Rita and Ricky have split for good this time. It is amicable between the two and they both made the decision to call it a day due to their work schedules.
"They've been on and off for a while. He's based in LA and she's based in London. Now that she's doing the X Factor and has her new album here, she will be here for the rest of the year. But he has commitments to his music career and fashion line overseas, too."
