She happily posed with Peter when he won the internship.

Peter received a three-month internship with Stella McCartney in a department of his choice, and all four finalists received internships with Lenovo’s design innovation team at their North Carolina headquarters.

It’s been a busy few months for Stella.

Earlier last month, she celebrated her Paris Fashion Week show and was supported by her family at the coveted event.

She also recently launched her new sustainable skincare line called STELLA.

In September, she revealed she got her father Paul his own skincare line for his 80th birthday and spoke about her late mother Linda.

She told The Telegraph at the time: “He’s going to love it, he was really mourning my first skincare line.”

Stella went on to speak about her relationship with her late mother, Linda, who died of cancer in 1998 at the age of 56.

She openly admitted that she wants to do things in life that her mother never had the opportunity to do.

“I rode my horse there the other morning and lived my best life and thought all that matters is that I can do all the things that I want my mother to do,” she said.

Stella also said the goal has carried over into her professional life, as she believes her mom would “love” and “trust” her new clean and beauty line.

She said her business means “so much” to her and said she wants to try to make a difference in the world like her mother Linda, an animal rights activist, did.
