Music video round-up: Beyoncé, Mariah, Green Day

Digital Spy rounds up the best music videos of the past seven days, so you no longer have an excuse to be out of the loop.

B.o.B ft. Nicki Minaj: 'Out Of My Mind'
B.o.B is going a little crazy in his latest music video. Unfortunately for him, Doctor Minaj is probably more crackers than he is.



Mariah Carey: 'Triumphant (Get 'Em)'
We never had any doubt Mariah would make an insanely good boxing match scorecard holder. We just wish the accompanying track was a KO rather than just OK.



Tulisa: 'Live It Up'
When Tulisa's not judging popstar wannabes on The X Factor it seems she parties on the beach with US rapper Tyga, people who like to play with fire and girls who wear Puma-branded shorts.



Beyoncé: 'I Was Here'
When it comes to doing a good deed, most people chuck a few quid at Children In Need every November. Beyoncé, however, records a new music video and brings World Humanitarian Day to the attention of over a billion people.



Green Day: 'Oh Love'
The American pop-punk trio make a return to music and they've brought some very seductive, model types with them for the ride.
