British singer-turned-fashion designer Pearl Lowe is celebrating eight years sober.

The former Powder frontwoman, 42, managed to kick her drug demons once and for all in 2005, and, on Thursday (07Mar13), she marked a new lifestyle milestone.

Taking to her Twitter.com blog, she writes, "I've just realised that I am 8 years clean & sober today."

Lowe's model daughter with ex-boyfriend Gavin Rossdale, Daisy, showed her support for her mum by responding to the post with the message, "So proud of you mumma (sic) - love you".
