Beyonce's kid sister Solange has just stuck a new version of a cut from her recent True EP online and its outro boasts none other than rapper-of-the-moment Kendrick Lamar. Head over to iTunes to get 'Looks Good With Trouble' or give it a digital spin here.

The pair are also busy doing their separate things. Ms. Knowles recently released a mini-video for 'Locked in Closets', in which the singer gives us a short tour of Brooklyn. Check it out below.

Meanwhile, Kendrick's debuted a new, funeral-based video for 'Bitch Don't Kill My Vibe'. Again, below!
