The couple were rumoured to have parted ways last week, but talking to Extra, the 38-year-old Bad Teacher actress brushed the speculation to one side.
'If I want to read gossip, I read about somebody else's life,' she said. 'I can't worry about what other people say. It's fine to say whatever you want as long as you actually don't know what's going on in my life.'
She also explained how she manages to maintain her slim figure, admitting that she has had to make changes to her diet as she has got older.
'I've become more disciplined on my diet, which I never had to do because I was skinny,' she said.
'I decided as you get older, it does change. I used to be able to eat fried chicken at two in the morning with a boat of gravy and French fries and mashed potatoes and not even feel it in the morning. Now, if I do that in the middle of the day, it's like, ugh.
'I've taken fried foods out of my diet on a daily basis. Every once in a while, I indulge in it, but I don't order the French fries every time. And I've had a longstanding love affair with French fries. I will always hold them dear to my heart.'
