This June, the Dropkick Murphys and Flogging Molly are joining forces for an Irish-rock double-bill tour. The 16-date tour will wrap up with an unusual megashow: between sets at the Bank Of New Hampshire Pavilion in Gilford, N.H. on June 23, boxers will face off in a series of fights promoted by Dropkick Murphys bassist Ken Casey.

Casey's been in the boxing biz for the past several years, promoting mostly fighters from — you guessed it — Boston. In the past, the Dropkick Murphys have incorporated boxing matches into their St. Patrick's Day shows. "Watch a band, then watch a fight, then watch a band and then watch a fight," says Casey. "People love it." (Billboard)

The Dropkick Murphys and Flogging Molly — sans boxers — will play at the Armory in Minneapolis on June 8.

American Idol crowns a winner

It's been a big week for Iowa native Maddie Poppe, who was both crowned the winner of ABC's American Idol reboot and shared the news that she's dating runner-up Caleb Lee Hutchinson. On Monday night's finale, Poppe sang her hit "Going Going Gone" with the help of her fellow contestants and judge Katy Perry — who's, meanwhile, probably dating Orlando Bloom again. (Billboard)

Earlier in the show, Poppe was paired up to sing a "Rainbow Connection" duet with Kermit the Frog, and thank goodness they didn't try to bring out Paul Williams. (Billboard)

R. Kelly sued for sexual battery

R. Kelly has been sued by Faith A. Rodgers, a woman who says that when she was 19, she entered into a relationship with the R&B star that included sexual battery, false imprisonment, and failure to disclose a sexually-transmitted disease. The New York lawsuit seeks unspecified damages, and comes as the latest in a cascade of consequences for Kelly, who recently became one of the first artists to be intentionally excluded from Spotify-curated playlists for non-musical reasons. (New York Times)

Meanwhile, the Pitchfork Music Festival has apologized for booking Kelly as a headliner in 2013. "It was wrong to book R. Kelly to perform at our festival in 2013 and we regret doing so," organizers said in a statement. "Pitchfork supports the work of journalists and organizations who have brought the allegations against him to light." The festival is now partnering with the Rape, Abuse & Incest National Network to "raise awareness and funds to support the fight against sexual violence." (Teen Vogue)

Grimes c

There's a precedent for musical artists like k.d. lang and jeremy messersmith asking that their names be stylized with lower-case letters, but the artist professionally known as Grimes is taking it to another level. Born Claire Boucher, Grimes says she's now legally changing her name to "c" — as in, the mathematical symbol for the speed of light in equations like E=Mc².

"Claire has been the bane of my existence since I became sentient," tweeted Grimes. "I can barely say it with my speech impediment, although c is technically worse for the lisp." Her friends already call her "c," she says, and her boyfriend Elon Musk, with whom she's bonded over science, reportedly thinks the new name "rox." (NME)
