PSY became a pop music sensation with his song "Gangnam Style" and now the South Korean rapper has treated himself to a new $1.25 million condo that he paid for all in cash, according to TMZ.

The two-bedroom, 2,700 square foot apartment is in the 29-storey Blair House, which is near Beverly Hills. The 34-year-old, whose real name is Park Jae-Sang, reported made more than $7.9 million from his hit song in the past few months after it topped the charts all over the world. The music video for "Gangnam Style" has amassed over a billion views on YouTube, beating Justin Bieber's "Baby" and making it the most watched video ever.

Gangnam Style" became on Friday, Dec. 21, the first video in the history of the Internet to reach and surpass one billion views, according to Billboard. The milestone comes just 27 days after PSY's music video broke the 803 million YouTube views record set by "Baby."

 "Gangnam Style" continued to have over 6.5 million views per day, calculated into 76.4 view per second, Billboard reported. The song's famous horse-riding dance has been performed by fans and celebrities around the word.

PSY and MC Hammer performed "Gangname Style" at this year's American Music Awards, which got celebrities out of their seats and joining in. PSY started the performance with his original song and dance, and then Hammer came on stage and joined in with a "Stop, Hammer time" add-in. The two performers then began doing moves from Hammer's "U Can't Touch This" video and ended the performance with the "Gangnam" dance. Both singers wore iconic 1990s Hammer pants.

Earlier in December, PSY apologized for performing an anti-America song in 2004 with lyrics that included "Kill those [bleep]ing Yankees who have been torturing Iraqi captives . . . Kill their daughters, mothers, daughters-in-law and fathers. Kill them all slowly and painfully."

He said he was "deeply sorry" for any pain he "caused by those words" and how the lyrics could have been interpreted.
