New music videos: Zowie, Beyonce, Gaga & SuBo

You don't want to cross Zowie - the Kiwi pop star has a baseball bat and an attitude, and she's not afraid to smash things.

Her new single Smash It - the follow-up to Bite Back - has just been released and it proves that Zowie is in a destructive mood.

She's just one of several pop stars to release new videos this week, including Lady Gaga, Susan Boyle and Beyonce.

Also released this week is Lady Gaga's duet with Tony Bennett, The Lady is a Tramp.

It's a change of pace for Gaga, who can usually be seen writhing and cavorting along to sexually charged songs while shouting controversial slogans and wearing revealing costumes.

Here she acts the part as a 60s diva as she shares the spotlight with 85-year-old crooner Tony Bennett.

The song is taken from Bennett's new album, Duets 2.

It's not on YouTube, but here's Beyonce's new video for her single Countdown, in which the pregnant diva shows off a short new 'do.

And here's Susan Boyle's You Have to be There, a song written by legendary Abba duo Benny Anderson and Bjorn Ulvaeus.

If you need a bit of testosterone after that lot, check out DJ Shadow's new clip for the very heavy track Border Crossing, from his new album The Less You Know the Better.
