Jennifer Aniston found her wedding to Brad Pitt ''stressful''.

The former 'Friends' actress tied the knot with the actor in 2000, but her wedding planner Kevin Lee admits his famous pal was uncomfortable with the lavish celebration - which cost a rumoured $1 million and included a 13 minute-long fireworks display and 50,000 flowers -and is planning a very different ceremony when she ties the knot with Justin Theroux later this year.

Kevin said: ''They won't be blowing millions on an over-the-top wedding with hundreds of people they barely know. Brad wanted that when she married him, and she got caught up in having a huge day.

''It was ultimately so stressful that she couldn't really take time to enjoy it. So it's going to be small and low-key so they feel relaxed.''

Instead, Kevin - who owns party-planning company LA Premier - believes the couple will opt for a ''sweet, romantic'' celebration.

He told Grazia magazine: ''She's so in love, she's found her soulmate, and really, that's all that matters.

''It's about celebrating and spending time with family and their closest friends. There will be a meaningful ceremony with heartfelt, loving vows and a wonderful meal. Jen's pure class and style, so expect lots of sweet, romantic touches.''
