The singer is reportedly facing 13 new charges, including child abuse images and obstruction of justice, according to the US Attorney's Office in Chicago.
The 52-year-old was arrested by NYPD and Homeland Security officials.
He's already pleaded not guilty to more than 20 sexual offences.
For two decades R. Kelly - real name Robert Kelly - has been accused of different sexual abuse allegations.
They've been brought back into the spotlight following the documentary series Surviving R. Kelly, which detailed stories about him pursuing teenage girls going right back to the start of his career.
The R&B artist was charged with 10 counts of aggravated criminal sexual abuse in February. He pleaded not guilty and has been released on bail.
Then in May he was charged with 11 more sexual offences, relating to sexual assault and abuse of a minor aged between 13 and 16, which he pleaded not guilty to last month.
It is not yet known whether the new federal charges are linked to the same cases.
A person can be charged with a federal crime if they've broken laws in more than one state. The charges are generally more severe than state charges.
R. Kelly has stood trial on sexual offences once, being acquitted of child pornography charges by a jury in 2008.
