It was a big night for Jennifter Aniston on Monday as she attended the premiere of a film she had directed.

However, perhaps a strapless playsuit wasn't the best option for the actress due to the unsightly marks on her back.

The 44-year-old showed round remnants of a recent cupping treatment as she arrived at the Los Angeles screening of Call Me Crazy.

Cover up: It looked like Jennifer had put foundation over the red cupping marks in a bid to disguise them

Jennifer has used the ancient Asian practice of cupping to stimulate circulation for over six years.

It involves placing glass cups on the skin either via suction or heat and has been used by stars including fellow Brad Pitt ex Gwyneth Paltrow.

However, the after effects mean the recipient normally has red circular marks on their mark for between three to seven days.

So it appeared Jennifer had hoped to disguise them with some foundation, but the too pale colour showed up under the paparazzi's flashes.

The 44-year-old is behind the camera again for Lifetime after earning plaudits for her piece within an anthology of films dealing with breast cancer - entitled Five - which was a hit with the same cable channel last year. 

Aniston is an executive producer behind the new film, which deals with the still stigmatised issue of mental health. 

Marta Kauffman, Kristin Hahn, Kevin Chinoy and Francesca Silvestri, all of whom executive produced last year's Five, also returned. 

Call Me Crazy has a stellar cast littered with names like Jennifer Hudson, Melissa Leo and Octavia Spencer, Sarah Hyland, Laura Dern, Brittany Snow, Melanie Griffith, Ashley Judd and Bryce Dallas Howard.
