"Uptown Funk" funked them up. Again.

Bruno Mars and Mark Ronson are in the hot seat once again over their hit single "Uptown Funk" as another lawsuit rises to the table.

A female rap trio called The Sequence is after the "Uptown Funk" duo claiming the song is very similar to their hit from the 1970s.

Called "Funk You Up," the trio's track was the third rap song to reach Billboard's Top 50 singles. According to TMZ, The Sequence says the 2014 hit has "significant and substantially similar compositional elements" to their hit single.

The members are now calling for a trial and for an unspecified amount of money from Mars and Ronson.
