Singer Christina Aguilera can achieve stunning red carpet looks and dons outrageous outfits when performing on stage - but the mother-of-one has said her life isn't all glamour.

The Voice USA judge told the MailOnline: 'There are two different sides of me. When Im at home being a mom, Im in my sweatpants and very comfortable so I can play with my son.

'And there's the side of me that gets out on stage and is quite the extrovert and the artist. Its always important for me to express that side of myself as well. This is balancing me and helps me to look my best.'

Glamorous: But when she's not working, Christina Aguilera said she loves to chill out in sweatpants

The Burlesque actress, 32, who is mother to son Max, four, admitted that being a working mum 'isn't easy' so she tries to find time for some relaxing pampering when she can.

'If I have more time I always try to go for a massage, I think that women, especially moms should take time for themselves,' she said.

She added that she also loves getting 'modern and funky' manicures from Dashing Divas DesignFX which suit her busy schedule because 'there is NO dry time, just apply and go.'

Her other beauty tips for busy women on the go include using dry shampoo, to give your hair some extra volume without having to wash it, and simply wearing red lipstick.

Beauty secrets: The singer said red lipstick always helps her feel sexy while her glowing skin is thanks to her nightly cleansing and moisturising regime

She said: 'Red lips are my must have. Red makes you feel instantly sexy and radiant. Its a confidence boost.

'I love a lipstick from LipSense called Blu Red and I always use a lip moisturizer before applying it. My favorite is By Terry Rose Balm because it softens my lips quickly so they always look smooth and flawless.

'Some women think that red lips dont suit them but its just a matter of finding the right shade that is best for you. They come in warm and cool tones and so many different shades the choices are endless!'

The singer confessed that while she tries to do her best to keep her skin glowing by sleeping and eating well, staying hydrated and cleansing and moisturising every night, she also has a trick up her sleeve to hide imperfections.

Family time: The star said when she's not working she prefers to dress comfortably so she can play with her son, Max

She said: 'Since I wear makeup for several hours at a time, its important for me to! keep up ! a good beauty regimen. Before I go to bed, I use a gentle cleanser, moisturize, and apply under-eye cream, which always feels good.

'My favourite foundation is Laura Mercier Crme Smooth Foundation. I love the creamy consistency, as my skin is rather dry. Plus it has wonderful coverage to hide any imperfections. I do love and try a lot of products.'

But beauty products and lifestyle tips aside, the Beautiful singer, who has had to face critics who have lambasted her in the past for being overweight, said the real key to looking good is confidence.

'When you are confident, you can feel feminine and sexy, even after a few sleepless nights,' she said.
