Adriana Lima finds being a mother is much more rewarding than being a model.

The Victoria's Secret beauty gave birth to daughter Valentina in November and is enjoying every moment of parenthood and can't believe the feelings of love she has for her little girl.

She said: "The best job in the world for me is being a mum. I never thought I could love so much. I always thought, does unconditional love exist? Now I know it does because I feel it.

"It's really changed me completely. I am, in my head, more mature, more secure. And, you know, it changed completely the priorities in my life. You feel so strong. It's such a wonderful feeling."

Adriana - who is married to handsome sportsman Marko Jaric - admits Valentina's birth was difficult as the Brazilian star was suffering from the potential fatal pre-eclampsia and had to deliver her baby six weeks early.

She told People magazine: "She weighed just 4.4 lbs and was the smallest baby in the whole hospital. I wish I had her at home but it wasn't possible in my case."

Adriana is now modelling again for Victoria's Secret after getting back into shape with lots of exercise and a strict diet.
