Lily Allen argues at first contact with her secret sister. Lily found out two years ago she had a half sister when her dad had an affair, but didn’t make any contact until recently. The ordeal didn’t go over well for either party.

More pictures of Lily after the leap…

Lily called her sister, who is going to college in the US, but it went downhill fast. The half sister complained about their father, Lily defended him, then the arguing started. From Now Magazine:

Lily had never met or spoken to her half-sister despite being just 5 years older and growing up a stone’s throw from where she lived in London.

Now can reveal that Lily, 24, took the decision to call the student, who now lives in the US, last month.

But the emotional phone conversation ended with both girls in tears – for all the wrong reasons.

A source close to the singer reveals: ‘Lily knows Gala’s been through a lot and she felt bad for her. There’s so much bad blood between Gala’s mum and her family that she knew 
it would be difficult.

‘The chat started well, with Lily offering to fly Gala and her mum over to London to meet her and her brother Alfie.

‘But then Gala told Lily how neglected she’s felt. Lily knows her dad hasn’t always been the best person, but she defended him. Before long, they were arguing.’

 That’s too bad they argued, but really. Lily makes Elton John mad, why is this a surprise? Lily, hopefully, can calm down and try again.
