Britney Spears has reportedly sent pop rival Christina Aguilera a self-help guide to marriage.
The sexy star bought the blonde singer - who recently tied the knot with lover Jordan Bratman - a tome entitled 'How to Stay Happily Married'.
The singers have only recently called time on a bitter feud, which was sparked after Christina reportedly got up close and personal with Britney's ex Justin Timberlake at London's Brit Awards.
Christina, who first knew Britney as child co-stars on the 'Mickey Mouse Club', sent the 'Toxic' singer a gift basket to mark the end of their feud.
She revealed: "I sent Britney a gift basket, and she phoned me to say thanks."
Christina admitted the pair have a lot of catching up to do, and said she still can't believe Britney is married with a baby.
She said: "I still can't believe Brit has had a baby! It's weird, you've known this person since she was a girl and now she's doing all these grown up things. It's been quite a journey for both of us."
