In an interview with the Sunday Mirror, Kristen Stewart's mother, Jules Stewart, confirmed her daughter’s relationship and said the pair are very happy together.

“What’s not to be accepting about her now having a girlfriend? She’s happy,” she said.

“She’s my daughter, I’m just her mum so she knows I would accept her choices.

“I’ve met Kristen’s new girlfriend, I like her. What’s not to accept? She’s a lovely girl.”

The 55-year-old script adviser went on to say her daughter’s bisexual and that everyone should be “free to choose” who they want to be with.

“I feel like people need to be free to love whoever they want. I accept my daughter loves women and men,” she said.

“It’s OK to be who you are in my world. We all choose our friends so we should be free to choose our lovers.

“People are good to do whatever they like as long as they’re not hurting people or breaking the law.

“I have gay friends, family members, I’m accepting of people, we are all free to choose who we want to love.”

The 25-year-old Twilight star’s relationship with Alicia comes two years after her split with long-term boyfriend and co-star Robert Pattinson.

Their romance ended after she was seen kissing "Snow White and the Huntsman" director Rupert Sanders — who was married at the time.
