Alfie Allen (pictured with Lily) has confronted his sister's former lover Ed Simons about their recent split - not long after Lily suffered a miscarriage
Chemical Brothers DJ Simons was reported to have broken up with Lily Allen last week, and according to the Daily Star Alfie is angry with Simons' behaviour.
He hunted down the DJ in North London and had to be dragged away by his girlfriend Jaime Winstone, say reports.
"Alfie is very protective of his big sister and wants to knock Ed’s head off his shoulders," said a source.
"Lily has just suffered the upset of a miscarriage and now Ed has ended their relationship and she is really struggling to deal with the heartbreak. Alfie talked with her after she’d met up with Ed again and got it into his head his sister was being messed around.
"On Friday night, he decided he needed to have a word with him and tracked him down to a pal’s house in North London. It was the early hours of the morning and he wasn’t let in so he just screamed that he wanted a word with him and that he should know why.
"But he was dragged away by Jaime. She was heard telling him to ‘just leave it’. He wanted to bring Ed to account."
