Jon Hamm has no desire to marry girlfriend Jennifer Westfeldt.

The 'Mad Men' actor has been with the stunning actress for 15 years and he says they have no plans to tie the knot as they are as happy as they are.

He said: ''We've talked about it, and we never say never. But it seems to us that weddings are sometimes more for the couple's family than for the couple themselves. Besides, neither of us has the greatest family history to point to in that department. Jen's parents' marriage ended when she was very young, my parents' marriage was over by the time I was two.''

Jennifer, 42, seems to be in agreement with 41-year-old Jon as she says they know how happy they are.

She said: ''We don't need a piece of paper to prove anything to ourselves or to anyone else. Our relationship we have is working for us, and we're in no hurry to change it.''
