Sienna Miller admits she 'didn't expect' age-gap romance

The actress revealed she never intended to end up with a man 15 years her junior, much less have a child with him. Sienna, 42, explained she initially thought her romance with fellow actor Oli Green, 27, was only a fling. "I didn't expect to take it seriously and then quite quickly, I fell in love.". "I wasn't like, 'I'm gonna get a younger boyfriend.' It was more, 'F**k! Why are you young? That's so annoying'.". However, she went on to explain she believes men of Oli's generation are more respectful towards women than men her own age have been.
