Star Magazine talked to Ramy, the makup artist who prepared her face for her David Letterman appearance a few days ago.

What was Britney's mood like when you worked on her?
This was my first time working with her. She was fine. She was really sweet, really cute, trusting. She didn't even look when I did her eyebrows. She loves everything. She said just do smoky eyes and dewy skin and everything else just do what you want. Something that was unusual was that I didn't have to change anything. I showed her the makeup and she just loved it. She just was really easygoing. Really seemed happy to get her hair and makeup done.

As a make-up artist looking close at her face could you tell if she had been crying, lost sleep, tired eyes, acne etc.?
I'll tell you, she looked amazing for someone who just had a baby. You would never know she had a baby 8 weeks ago. Her figure was fantastic. She had a little bit of blemishes on her face but overall I say she was surprisingly good. I saw her after they did her hair. She looked like a young kid. She looked great and her stomach was flat. You would never know. There was no flag. I can't say she looked like she was crying, nothing like that. She really looked fine. I think if anything her mind-set is moving forward and getting on with life.
