Jennifer Lopez has managed to knock Adele's 'Someone Like You' from the top spot and is now sitting pretty at number 1 with her anthem, 'On The Floor'. 

This single is the first to come from JLo's forthcoming album, 'Love?', and features Pitbull, which is clearly a winning combination because the new entry (April 3) has gone straight to the top. She also tweeted to fans yesterday, April 2, that she's currently filming the video for her next release and shared some photos from the set. 

Katy B's 'Broken Record' was the only other new entry in the singles chart this evening at number 8 and LMFAO's 'Party Rock Anthem' climbed an impressive 19 places to 3.
