Christina Aguilera's romantic hikes

Christina Aguilera has revealed she likes to take romantic hikes with her boyfriend Matthew Rutler but hates the casual footwear she has to wear for them.

The 'Voice' mentor loves spending time with Matthew Rutler but admitted the footwear for hiking is not her usual choice.

She said: 'My boyfriend and I started hiking. He got me in a pair of sneakers - no heels, no red soles. So out of character for me.'

Christina also revealed her son Max, four, - from her marriage to Jordan Bratman - doesn't mind when paparazzi follow them.

She explained: 'Paparazzi followed me at my son's soccer game the other day. I was complaining but he said 'Don't worry Mama. They're not taking pictures of you, they're taking pictures of me.'
