Couple: Jason Segel & Linda Cardellini
The show that established Judd Apatow’s career was also responsible for the wonderful friendship between two of its co-stars. On the set of the programme, Linda Cardellini and Jason Segel fell in love. The fact that Nick and Lindsay were on-screen lovers made it easier for them to get to know each other.

Despite the show’s finale, they continued in a relationship for another five years after it finished. In the end, they had no choice but to call it a day. Forgetting Sarah Marshall, Jason Segel’s smash-hit film about a breakup, is reported to be based on his own breakup with Cardellini.
