Sadie Frost is chasing the ''perfect relationship''.

The 'Love, Honour and Obey' actress turned 50 last week and has admitted she felt under ''pressure'' to achieve everything she's ever wanted as she approached the milestone birthday, including finding the right man.

In an interview with The Times newspaper, she explained: ''I wanted to be able to tick all the boxes, so I put expectations on myself. I am happy with my career, I am happy with my kids, so it was 'now I want the perfect relationship'. There is always something, but if you put too much pressure on yourself you implode.''

The sexy star - who has 24-year-old son Finlay from her first marriage to Spandau Ballet's Gary Kemp and children Rafferty, 18, Iris, 14, and Rudy, 12, with second husband Jude Law - is now rumoured to be ''loosely'' seeing multi-millionaire Darren Strowger.

However, Sadie - who was given a warning for assault by police in 2012 during a row with her former boyfriend, model James Gooding - confessed she needs to learn to be more tolerant in her relationships, as her lack of patience in this part of her life has been an issue.

She added: ''I have got a lot of tolerance and patience in most areas of my life. It's when I come to relationships that I need to practice patience and tolerance.''
