Colton Haynes has ''no nerves'' about his upcoming wedding to fiancé Jeff Leatham.

The 29-year-old actor is currently planning his big day, and has said he won't be turning into ''bridezilla'' as he says that as long as his family are happy, the day will be a success.

He said: ''[I have] no nerves at all. Something like that is just so special. You just make sure everything's right and the family's happy and the friends are happy and that's all that matters. And the grooms are happy. No bridezillas here.''

Mostly, the former 'Teen Wolf' star is looking forward to being able to relax once the stress of planning the nuptials is out of the way.

He added to Us Weekly magazine: ''I'm just excited for everything to calm down. The planning of everything is a lot, but also having this party and everything is just a lot. Once everything kind of calms down in the next couple of weeks, then I'll be good.''

Colton and the celebrity florist got engaged in March this year when Jeff popped the question during a romantic getaway to the Las Ventanas al Paraiso resort in Cabo, Mexico, where he enlisted the help of his pal Cher, who appeared on a big screen to offer some words of advice.

Colton previously shared a picture of himself and Jeff embracing with fireworks lighting the sky above them, and Cher visible on a giant display.

He captioned the Instagram post: ''Thank you @cher for the beautiful ''I got you babe'' proposal lead in, you sounded incredible as always :) The most special night of my life @jeffleatham . #flowers #fireworks #fullmoon #cher (sic)''

Two months later, the 'American Horror Story' actor surprised Jeff with his own proposal, and Jeff took to social media to celebrate the news.

He posted a sweet picture of them together, showing off their engagement rings, and wrote: ''I SAID YES !!! Not a bad day when you find YOUR engagement ring in a glass of vintage #domperignon and of course with Cher's ''I Got You Babe'' playing in the background - I Love YOU @coltonlhaynes - Now we are both engaged baby !!! Let's get married - I Love you - Love You - Love You #doubleengaged (sic).''
