British singer Amy Winehouse cancelled her Los Angeles concert last night to give herself time to get over her recent heartbreak.

Winehouse, 23, was devastated when she split from chef boyfriend Alex Jones-Donelly earlier this month and due to her busy concert schedule in her native Britain and America, she hasn't had the chance to grieve the loss of the relationship.

The star was set to perform at Spaceland last night, but pulled the plug on the gig earlier in the day. Winehouse also canceled two concerts in London on 8-9 March, citing, "unforeseeable circumstances". A concerned friend says, "Amy loved Alex so much and was so upset when they split.”

"Normally she would take time out to wallow like most normal young girls, but she's just been on the road performing and doing interviews non-stop. She's exhausted and miserable. She doesn't feel she can give the audience her best while she feels this sad."
