Lady GaGa has topped both the UK album and single charts.
The American singer's debut album 'The Fame' climbed to number one on Sunday, joining her song 'Poker Face', which was already at the top spot in the singles countdown.
The feat comes in the same week that Lady GaGa became the first artist in a decade to top the US Billboard Hot-100 with her first two singles.
In what was a slow week for new albums, Kings of Leon's 'Only By The Night' remained at number two, while Annie Lennox's 'The Collection' was at three.
Ronan Keating's 'Songs For My Mother' fell three places to number four.
Rapper Flo Rida's album 'Roots' was the only new entry in this week's top-10 at number five.
