Despite Bruno Mars's best attempts, LMFAO
scored a third week at the top of the singles tally last Sunday, while Adele fended off The Wombats to continue her record-breaking reign atop the albums chart. With new releases from Blue, David Guetta and Jennifer Lopez this week, where can we expect to see them chart come Sunday evening? LMFAO look likely to notch up a fourth week at number one with 'Party Rock Anthem', with Bruno Mars's 'The Lazy Song' still chasing their tail.Blue's Eurovision entry 'I Can' is on course to enter the lower half of the top ten - their 12th such entry in total if they manage to cling on until the end of the week.David Guetta, Flo Rida and Nicki Minaj's rush-released 'Where Them Girls At' is currently at the edge of the top 15, while Wynter Gordon's 'Dirty Talk' is knocking on the door of the top 25.Further down the chart, Lady GaGa's 'Judas' has slipped to the rim of the top 30, and Dev and The Cataracs' 'Bass Down Low' has snuck in at the bottom of the top 40.On the albums chart, Adele's 21 is swatting away Fleet Foxes' Helplessness Blues, while Radiohead's King Of Limbs has soared back into the top three.Jennifer Lopez's comeback LP Love? currently sits just outside the top five, with the Beastie Boys' Hot Sauce Committee Part 2 a place behind her.How do you think Sunday's Official Charts will shape up?
