Rihanna has beat Janet Jackson's record to claim the title for the second-most No. 1s ever on the Billboard Dance/Club Play chart. Her run of now 20 No. 1s started with her debut single "Pon De Replay." Reuters

Rihanna has conquered another dance music queen thanks to her latest No. 1 single on the Billboard Dance/Club Plays Songs chart, "Right Now."

The hit track makes her 20th No. 1 song on the chart, placing her in the second spot for the most No. 1s in the chart's history, reports Billboard. With her new chart topper, Rihanna now moves past Janet Jackson, who holds a more than commendable 19 songs that have landed in the chart's lead spot. But Madonna continues to be the dance singles champion with 43 No. 1s.

As a testament to her hit-making power, it should be noted that all 20 of Rihanna's No. 1s were earned in less than a decade. Her debut track "Pon De Replay" kicked off her chart domination on Oct. 8, 2005. '

Unlike most of her smash dance singles, though, "Right Now" didn't always seem destined for chart success.

The track initially debuted on the chart at No. 50 in February. It peaked at No. 33, falling completely off the chart toward the end of April. But with an added nudge from the release of several official remixes, Billboard reports the track re-entered the chart at No. 44. It officially claimed the No. 1 slot after six weeks.

And if RiRi's singles continue to stick to her current pattern, it appears there will be even more No. 1s in her future.

Look out Madonna! Your dance chart reign may soon be a distant memory.
