Sunday chart predictions: Beyoncé, Jason Derulo, Adele

Wednesday's official singles chart update saw Jason Derulo fight off competition from Example to retain his number one position with 'Don't Wanna Go Home', while Beyoncé dominated the album chart with her fourth studio album 4. The big question is, have they managed to keep posession of their coveted top-spot positions? We take a final look at the charts ahead of this Sunday's official run-down.

Jason Derulo's 'Don't Wanna Go Home' is just managing to remain at the top, with competition now coming from Beyoncé's 'Best Thing I Never Had'.

Example's 'Changed The Way You Kiss Me' has slipped a place to complete the top three, pushing Ed Sheeran's 'The A Team' down a spot too.

Adele continues to gain momentum with 'Set Fire To The Rain', which edges even closer towards the top 20, while Jennifer Lopez also gains 3 places to land at number 22 with 'On The Floor'.

Further down the chart Enrique Iglesias's 'Dirty Dancer' moves up a spot, while Coldplay's Glastonbury performance of 'In My Place' slips a few to 34.

Beyoncé could be on course to make it a chart double, with her new album 4 still riding high on the album chart, continuing to fend off competition from Adele's 21.

A new entry from Stevie Nicks with In Your Dreams falls a couple of places, while Kaiser Chiefs stay firm at number eight with The Future Is Medieval.
