Joel Kinnaman thinks Olivia Munn talks too fast.

The 33-year-old American actress admits her Swedish beau, whom she has been dating since 2012, tells her to slow down when she is speaking to him because he has difficulty keeping up and understanding her.

Speaking in the May issue of Redbook magazine, she explained: ''He tells me 'Baby, slow down! I cannot understand you.' And I think to myself, 'Just listen faster!'''

The brunette beauty and the 34-year-old hunk first sparked rumours they were dating after they were spotted at the second season premiere of 'The Killing' in Los Angeles in March 2012 together, and a friend at the time claimed they had bonded over their similar sense of humour.

An insider said two years ago: ''He is a super-normal guy and she is a really down-to-earth girl and they just get each other.

''They are on the same wavelength intellectually, and they have the same sense of humour. It's been going on for a little while and it's heading towards being serious. They are extremely happy together.''
