Charlie Sheen has taken to Twitter to apologise to Rihanna after calling her a "b***h" on live television

Writing on the site on Tuesday (17.01.17), the 'Mad Families' actor said: "dear @rihanna, pardon my inane self indulgence. let's have a drink someday (on me) .... (sic)"

The comments come after Charlie was previously involved in a Twitter feud with the 'Work' hitmaker when she shunned his request for her to meet with his then-fiancee Scottine Ross because she was a big fan.

During his appearance on Andy Cohen's talk show, Charlie was asked if they had resolved their differences from three years ago, to which he responded: "Oh, that b***h."

When Andy noted he may have just made the situation "worse", he replied: "No, she abandoned common courtesy and common sense."

And it wasn't just the 28-year-old singer who found herself slammed by the 'Platoon' star, as he also hit out at many of his former co-stars.

Asked to rank some of his former female colleagues in order of favourite to least favourite, it seemed only his 'Spin City' co-star Heather Locklear has left a lasting good impression on him.

Tasked with ordering Jenny McCarthy, Selma Blair, Heather, and Lindsay Lohan, he said: "Heather. And then Heather."

And when Andy pointed out he hadn't mentioned the others, he said of his 'Scary Movie 5' co-star: "Lindsay's a trip. She's work, but she's cool. She's fun to look at."

But of Jenny, who played his love interest on 'Two and a Half Men' and Selma, who was written out of 'Anger Management' because they didn't get along, he said: "I would like to kind of mash those two up together and just kick 'em to the curb, they deserve each other."
