Amy Winehouse has left hubby Blake Fielder-Civil “devastated” by spending a night in a hotel room with music producer pal Mark Ronson.
The unlikely pair – who worked together on hit album Back To Black – were seen heading back to Mark’s hotel room at 5.30am on Saturday, after a boozy session in a recording studio on Friday night.
Wino didn’t emerge from the K West Hotel in Notting Hill, west London until midday.
Her Blakely - who is currently being held on remand at London's Pentonville Prison on charges of perverting the course of justice - is said to be devastated by his missus’ behaviour.
A source tells News Of The World: "It's the last thing Blake needs to hear right now. He's furious about how close they are.
"Blake's fearful that Mark has much more in common with Amy than he does and is worried he'll steal her away."
We caught the newly-blonde Wino heading back to the hotel with her new companion - and for what it's worth, we don't think Blakey has anything to worry about.
Check out the bleached mess here.
