Even though rumour has it that the sisters have fallen out, they will also collaborate with the high street brand for a second collection.
The debut Penélope & Mónica Cruz for MNG range was launched in July this year and the next additions to the range are expected to hit stores early next year.
The ad campaign for the range has already been shot by Mert and Marcus and the new images will be doing the rounds in January.
Penelope is not stranger to the fashion world and she owns her own store called Amarcord, in Madrid.
She also signed a deal as the face of jewelry and handbag collections for the Japanese retail chain, Samantha Thavasa, earlier this year.
