Pussycat Dolls began recording music in 2003
Two members of chart-topping band the Pussycat Dolls have left the band, it has been confirmed.
Ashley Roberts announced on micro-blogging site Twitter that she had "an amazing ride" and had "learned so much".
She added she will "always love those girls. My sistas 4 life."
Kimberley Wyatt who recently judged Sky One's Got To Dance talent show left over the weekend saying "money and fame can't buy happiness".
In a statement, Roberts added that she has "gotten the acting bug and am falling in love with it. I have a few projects in the works and when ready I will announce more details to all of you".
She also said she is "in the studio recording some of my own music".
Roberts' and Wyatt's exits follow the departure of former group member Carmit Bachar, who quit the group in 2008.
It follows rumours of a rift in the group over the elevation of member Nicole Scherzinger to lead singer.
The pair are understood to be working on other projects
Scherzinger, who dated former F1 world champion Lewis Hamilton, has just been announced in the line up for US television show Dancing With the Stars.
Initially forming in 1995 as a burlesque troupe based in Los Angeles, the changing line-up settled on six members who began recording music in 2003.
Their single Don't Cha was number one in the UK in 2005 and a chat-topping debut album PCD followed in 2006.
