Justin Theroux didn't find planning his wedding ''fun''.

'The Leftovers' star, who wed Jennifer Aniston in August, has admitted the pressure of keeping the nuptials a secret made it a less than enjoyable experience.

He told the New York Daily News: ''I wouldn't say it was fun to plan. Part of the fun of planning a wedding is telling people and we had to keep it under wraps.''

The 44-year-old actor also claimed that he feels different since becoming a husband, although it hasn't radically changed his life.

He explained: ''I noticed it almost immediately. It was like your blood pressure goes down two PSI. It's not like life is completely different. It's a beautiful thing.''

The couple managed to keep their wedding a secret from their closest family and friends, who were invited to their Bel Air home under the guise of a birthday party for Justin.

Jennifer, 46, recently gushed about her marriage to Justin, saying she feels ''more confidence than ever''.

She said: ''When it comes to relationships, I'm a late bloomer. But I've learnt from my mistakes, am comfortable in my own skin and have more confidence that ever. In Justin, I have met my best friend - that's the icing on the cake!

''He is kind, honest, and generous and has empathy for other people ... I think that's amazing! The fact that he also has a dry sense of humour is a big plus.''
