The 40-year-old singer-and-actress is preparing to make a comeback with a world tour and new movie, 'The Back-Up Plan', two years after giving birth to twins Max and Emme – her children with husband Marc Anthony – and admits having such a long break has made her feel like she is starting out again.

She said: 'I feel like it's a new beginning. It's a bit like when I was a teenager about to embark on this career but it's much more challenging, difficult and harder.

'I have so much more experience now but I feel just as fresh as I did back then and I'm excited about my life.'

Despite enjoying her time at home with her family, Jennifer insists she has no plans to ever give up working.

She added in an interview with the Daily Mirror newspaper: 'I won't stop doing what I do. Maybe I'll get to a point where I'm tired and feel I've done enough, but right now I see myself always working and expressing myself – whether in music or movies or fashion or whatever. That's what I love to do.'
