"Heaven" becomes Mars' fifth Mainstream Top 40 No. 1, tying him with Nelly and Justin Timberlake for the most leaders among solo males. (Timberlake also made two trips to the top as part of 'N Sync, with "Bye Bye Bye" (10 weeks at No. 1) and "It's Gonna Be Me" (five), both in 2000.) Here is a look at the male soloists with the most No. 1s, dating to the Mainstream Top 40 chart's launch the week of Oct. 3, 1992:

5, Bruno Mars
5, Nelly
5, Justin Timberlake
4, Flo Rida
3, Chris Brown
3, Eminem
3, Ludacris
3, Timbaland
3, Kanye West

Katy Perry and Rihanna lead all artists with nine Mainstream Top 40 No. 1s apiece. Women, in fact, far outpace men when it's come to topping the tally; five other women have totaled between eight and six leaders each: Pink (eight), Lady Gaga, Britney Spears (seven each) Beyonce and Mariah Carey (six each). Christina Aguilera and Avril Lavigne, as well as Maroon 5, have also managed five No. 1s each.

Mars first ruled Mainstream Top 40 as a guest on B.o.B's "Nothin' on You," which crowned the May 22, 2010, ranking. His debut album, "Doo-Wops & Hooligans," which reached No. 3 in a 112-week (and counting) run on the Billboard 200, yielded Mars his first two Mainstream Top 40 No. 1s as a lead artist: "Just the Way You Are" (three weeks, beginning Oct. 30, 2010) and follow-up "Grenade" (five weeks, starting Feb. 5, 2011). He had last led with "It Will Rain," from the soundtrack to "The Twilight Saga: Breaking Dawn: Part 1," the week of Feb. 4.

"Heaven" introduces Mars' second album, "Unorthodox Jukebox." As previously reported, the set is projected to arrive in the top five of this week's Billboard 200.
