Kristen Stewart's sexuality has remained a mystery ever since she has been spotted getting cosy with her assistant Alicia Cargile.

The Twilight star and Cargile have been spotted on numerous occasions in Los Angeles sparking rumours that the two are in a lesbian relationship.

Putting all the gossip to rest Stewart has spoken up about sexuality and the obsession of the media in defining relationships.

In an interview, the 25-year-old actress told Nylon magazine, "If you feel like you really want to define yourself, and you have the ability to articulate those parameters and that in itself defines you, then do it. But I am an actress, man. I live in the f**king ambiguity of this life and I love it. I don't feel like it would be true for me to be like, 'I'm coming out!' No, I do a job."

"Until I decide that I'm starting a foundation or that I have some perspective or opinion that other people should be receiving... I don't. I'm just a kid making movies," she added.

The Clouds of Sils Maria actress also said that it is not be necessary for one to figure out their sexuality for a few years.

"I think in three or four years, there are going to be a whole lot more people who don't think it's necessary to figure out if you're gay or straight," Kristen claimed, "It's like, just do your thing."

When asked whom she is dating now, the actress remarked,"Google me, I'm not hiding."

The lesbian rumours surrounding Stewart and her assistant were fueled when her mother, Jules Stewart told the Sunday Mirror that she has met Cargile, and confirmed that they were dating.

The 55-year-old told the publication, "What's not to be accepting about her now having a girlfriend? She's happy. She's my daughter, I'm just her mom 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," she said.

"I feel like people need to be free to love whoever they want. I accept my daughter loves women and men. 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," Jules added.
