Lindsay Lohan insists she loves Big Macs, femalefirst.co.uk reports.

The actress has sparked concerns for her health after being pictured with an increasingly skinny frame, but has blamed her slim physique on her hectic work schedule.

“I eat. I had my Big Mac yesterday from McDonald’s. I eat just as much as I always have,” the website quotes her as saying. “I think I’ve just been working a lot. It’s just down to stress and lack of sleep when I travel. I think it’s all that stuff that adds up.”

The 22-year-old star won’t listen to criticism about her weight, adding she doesn’t want to be pressured into looking a certain way.

“I’m my own person, and people can say whatever they want. I’m still going to be the person that I am, and I think that’s so important for people in Hollywood.”

Lohan added she only cares about being happy and has learned to accept herself the way she is: “I think that I don’t ever want to pretend to be something that I’m not. I’m not perfect, nobody is perfect.”
