Christina Aguilera - Christina Aguilera's Lipstick Lovenotes

Christina Aguilera writes love notes to her husband in lipstick.

The 'Not Myself Tonight' singer said she lets her husband Jordan Bratman know she cares every day by leaving little notes for him to find around their house.

She said: "I leave little lipstick marks on the bathroom mirror for when he wakes up, and little notes written in lipstick on the mirror and in the shower.

"Little notes, little cards, little 'I love yous' here and there, just to keep things fun and alive."

Christina – who married Jordan in 2005 – said the secret to the success of their relationship is to always make sure they give each other "room to grow".

She added: "Everyone has rough patches, everybody grows and we all change. It's important to give each other room to grow and to accept them for who they are.

"We've been married for five years now, and I think the secret is in always keeping it interesting. You have to make time for yourselves"

The 29-year-old singer also said that music marketing executive Jordan hasn't been afraid to get his hands dirty when he needs to – chiefly when their son, Max Liron, now two, was born.

She added: "Having Max has brought us closer together. Jordan changed the first nappy while I was in bed recovering from my C-section - and he's been so hands-on ever since. When I see them together it makes my heart sing and melt at the same time."
