Los Angeles, Sep 28 (IANS): Actress Gwyneth Paltrow celebrated her 44th birthday by sharing a make-up free photograph on social media.

Paltrow, who turned 44 on Tuesday, posted the image on Instagram, reports aceshowbiz.com.

In the image, the "Iron Man" star can be seen rocking wavy hair and a floral top as she smiles at the camera and shows no sign of ageing.

"No make up for my 44th birthday, embracing my past and future. Thank you for the Instagram love," she captioned the image.

Staying pretty and ageless is not easy for Paltrow. In an interview earlier this year, she said that she tried everything and was even willing to undergo painful procedures to maintain her beauty.

"I'm always the guinea pig to try everything. I've got to try them all," she said.

"I love acupuncture. Also, I just heard of a service called a sound bath, which might be too hippie-ish even for the likes of me. It's some new healing modality. I might not be able to handle it," she explained.
