Katy Perry's 2012 has ended on a high note - the pop star has been named Billboard magazine's Woman of the Year.

The I Kissed a Girl singer kicked off 2012 in a slump after her former husband Russell Brand filed for divorce just before New Year, but chart success, a hit concert movie which chronicled her private life woes, and a series of high-profile concerts quickly put her back on top.

The 28 year old was presented with the 2012 Woman of the Year award in New York on Friday (30Nov12).

Meanwhile, newcomer Carly Rae Jepsen has been named Billboard's Rising Star.

The thrilled Call Me Maybe singer says, "It's been such an impossibly wonderful year and it just keeps getting better."
