Australian pop star Daniel Merriweather is celebrating nine months of sobriety by giving up meat.

The Change singer checked into a rehab clinic to sober up in the aftermath of a nasty car crash last December (12) which led to a drink-driving conviction earlier this year (13).

He is now nine months sober, and has decided to change his diet to mark the milestone.

In a post on, he writes, "Today I am 9 months sober... To commemorate my sobriety I am going to quit eating mammals. Sober life."
