Peter Andre's new girlfriend makes him feel young again.

The 39-year-old reality TV star is dating medical student Emily MacDonagh, 23, and feels like he's been given a new lease of life since they got together.

He said: ''I feel so young at the moment. I went through a stage where I was feeling my age but now I'm feeling good. I don't know if that has anything to do with, you know, my situation.''

Peter also admits he's had a fear of commitment since he divorced Katie Price - with whom he has two children, Princess, five, and Junior, seven - in 2009 after three years of marriage, and admits it prevented him from pursuing any of the women he dated before meeting Emily.

He added in an interview with new! magazine: ''Dates were just dates. No disrespect to anybody - and I liked those people - but I couldn't see them developing. I think that was my fault though as it's my commitment phobia. [But] it's getting closer. I've had this guard up for the last few years.''
