Need To Know: Rihanna Wins Big At iHeartRadio Awards

Plus: Miley hits a milli, and everything you might be up to this weekend.

iHeart Radio Hearts Rihanna

In the first-ever iHeartRadio awards Thursday night in Los Angeles, Rihanna was the center of attention and it wasn't for her increasingly legendary (frequently naked) Instagram pics. The pop megastar took home four prizes, including Artist of the Year and Song of the Year for "Stay" with Mikky Ekko. The show also featured a provocative performance of "Problem" from Ariana Grande, Kendrick Lamar's cover of Tupac's "California Love" and the debut of a brand-new Michael Jackson song featuring dancing from Usher.

Miley Hits A Milli

Despite persistent health problems that have forced her to cancel or delay numerous tour dates, Miley Cyrus' Bangerz crossed the 1 million copies sold mark, seven months after its release. That means Smilers only need to snap up another 2.7 million before it eclipses her best-ever selling album, the "Hannah Montana" soundtrack.

New Info In Peaches Geldof's Death

After her shocking death at age 25, a newly released toxicology report indicates that heroin was present in Peaches Geldof's body at the time and was "likely to have played a role in her death." Geldof's mother, Paula Yates, died at 41 of a heroin overdose in 2000.

Have A Web-Slinging Weekend

"The Amazing Spider-Man 2" swung into over 4,000 theaters with its eye on a $100 million-plus opening weekend. "Captain America: The Winter Soldier" holds the crown for biggest weekend take of the year with a cool $95 mil. Can Spidey over take Cap? Star Andrew Garfield will be doing his part by hosting "SNL" with musical guest Coldplay. After our late night showing of the movie, we'll no doubt be taking a disco nap to stay up late and see what happens in studio 8H.

These Aren't The Holidays You're Looking For

With Cinco de Mayo still three whole days away, it's not time to break out the fiesta just yet. Meantime, we'll be keeping ourselves busy with Free Comic Book Day on Saturday and Star Wars Day on Sunday.
