Kelly Clarkson's Mr. Know It All hits the Hot 100 as the highest debut at #18.
Her Stronger album will debut on October 25. The 18 spot isn't such a bad preview.
As for Rihanna, she's not doing so bad either! Cheers (Drink to That) has landed in the Top 10.
And knowing RiRi's singles, it will probably make the Top 5 pretty soon!
