Vincent Kartheiser had no idea who Alexis Bledel was when they first met.
Although Alexis found fame playing Rory Gilmore on long running drama 'Gilmore Girls', Vincent admitted he wasn't familiar with the show and had never heard of Alexis before meeting on the set of 'Mad Men'.
Vincent Kartheiser prepared for proposing to Alexis Bledel with some help from his 'Mad Men' co-stars.
The 31-year-old actress and the 33-year-old actor started dating after falling for each other on the set of the advertising drama last year and Vincent turned to his co-stars Elizabeth Moss and Jessica Pare when he decided to pop the question.
Hayden Panettiere is drawn to more experienced men.
The 23-year-old actress is in a relationship with boxer Wladimir Klitschko, 36, and previously dated her 'Heroes' co-star Milo Ventimiglia, 35, and insisted while she likes ''worldly'' people she didn't decide on ''older men''.
