It's a first for Rihanna, as her seventh album 'Unapologetic' has cruised into the No. 1 slot on the Billboard Top 200 album chart. It's RiRi's first time topping the leaderboard …ever! Congrats to the shirtless wonder of the pop world for this career first. RiRi is the top(less) o' the pops.

'Unapologetic' moved 238,000 copies its first week in stores, according to Billboard, which takes its stats from SoundScan, and that was enough to push the record into the top slot.

RiRi notched her 12th No. 1 single on the Billboard Hot 100 last week with 'Unapologetic' lead track 'Diamonds.' But it's pretty shocking that she never hit No. 1 on the Top 200 albums chart before. Until now, that is.

Those two stats allowed the Bajan beauty to score a strange and dubious record of having the most No. 1 songs on the Hot 100 without ever having a No. 1 album. She was always a bridesmaid and never a bride. This week, she's a bride.

'Unapologetic' was also her best first week frame. 'Loud' landed at No. 3 in 2010, moving 207,000 copies, and that was the most albums she had sold in a week at the time.

'Good Girl Gone Bad' debuted at No. 2 in 2007, while 'Rated R' landed at No. 4 in 2009. Last year's 'Talk That Talk' bowed at No. 3.

RiRi can scratch "Having a No. 1 on the Billboard Top 200" off her bucket list.

Congrats baby girl!
