RI-WARDED: As "What's My Name?" vaults 60-1 on the Billboard Hot 100, Rihanna continues to enhance a commanding chart history that began the week of June 11, 2005, when "Pon De Replay" debuted at No. 97.

"What's My Name?" becomes Rihanna's eighth No. 1 (and featured artist Drake's first), a sum bested by only four women in the Hot 100's 52-year history.

Here is a look at the solo female artists with the most Hot 100 No. 1s:

Total No. 1s, Artist, No. 1 Span
18, Mariah Carey (1990-2008)
12, Madonna (1984-2000)
11, Whitney Houston (1985-95)
10, Janet Jackson (1986-2001)
8, Rihanna (2006-10)
6, Paula Abdul (1989-91)
6, Diana Ross (1970-81)
5, Beyonce (2003-08)
5, Olivia Newton-John (1974-81)
5, Barbra Streisand (1974-80)

Of the women with at least eight No. 1s, Carey reached the total the fastest, as "Vision of Love" became her first leader the week of Aug. 4, 1990, and "Hero," her eighth, reigned Dec. 25, 1993, a span of three years, four months and three weeks. Rihanna is the second-quickest, requiring just four years, six months and one week between her first and latest trips to the top.

Dating to May 13, 2006, when "SOS" became the first of Rihanna's eight Hot 100 No. 1s, Justin Timberlake ranks second with four leaders, followed by the Black Eyed Peas, Eminem, Fergie, Nelly Furtado, Ludacris, Katy Perry, T.I. and T-Pain, each with three.

"What's My Name?" storms in atop Digital Songs, marking Rihanna's ninth No. 1 on the survey, the highest total since the chart's data began contributing to the Hot 100 the week of Feb. 12, 2005. Beyonce, the Black Eyed Peas, Eminem and Timberlake rank second in that span with five Digital Songs No. 1s each.

CAREY, DIAMOND SHINE: Two Billboard 200 titans pad their top 10 totals.

Mariah Carey collects her 16th top 10, as "Merry Christmas II You" bows at No. 4. The set complements Carey's first holiday release, "Merry Christmas," which peaked at No. 3 in 1994. Carey first entered the top 10 the week of Aug. 4, 1990, when her eponymous debut rose 13-10 on its way to an 11-week reign beginning March 2, 1991.

Neil Diamond logs his 17th Billboard 200 top 10, as "Dreams" debuts at No. 8. Diamond first reached the upper bracket with "Gold" in 1970 (No. 10). The singer joins Eric Clapton, Michael Jackson, Tom Petty & the Heartbreakers, the Rolling Stones, Santana and James Taylor as the only artists to appear in the top 10 in each of the last five decades.
