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."
Oddly, she was fine the night before, when Courtney Love and Bruce Willis were dancing round at her gig. Still, lets hope the party with Willis cheered her up, eh?
