Joe Manganiello wants Sofia Vergara to stop obsessing over their upcoming wedding.

The 'Magic Mike XXL' star has urged his fiancée, whom he is set to marry in Miami next month, she needs to relax more as their special day approaches.

A source told InTouch: ''All they talk about is the wedding.

''Joe is a very low-key guy. He loves Sofia and wants to give her whatever she wants, but the guest list has gotten completely out of hand and the whole thing has turned into a huge production. [He's trying to] remind Sofia what the day is really all about.''

The 'Modern Family' actress recently admitted she is very involved in the planning process.

Asked if she has become a so-called bridezilla, she said: ''I think I am beyond that.

''I am very detail-oriented so I am kind of like a nightmare. I have a very good memory. If you show me swatches of things, I can in two months exactly remember, 'What happened with the one with the little border that had the little print?' I'm like, really bad.''
