Khloé Kardashian ''always believed'' Kim Kardashian and Kanye West ''are soul mates.''

The 'Keeping Up with the Kardashians' star - who previously insisted that she was the one who convinced her sister to date the rapper because she knew he was in love with Kim for years - admits she was blown away by ''how calm and dream-like'' their wedding was in Florence, Italy last month.

The 29-year-old beauty told E! News: ''The peace in Kim and Kanye was undeniable. We felt as if they had been married in another lifetime.''

She added: ''I have always believed these two are soul mates.''

Kim, 33, and Kanye, 37, are currently soaking up the sun at a private villa on their ''second honeymoon'' in Mexico after enjoying a few days in Ireland and Prague following their nuptials at the Forte di Belvedere on May 24.

An insider said: ''It's been really nice for them to relax, just the two of them. After their time in Ireland, they really wanted some tropical sun.

''They've had the huge house all to themselves, other than the staff that is there waiting on them. They've literally been doing nothing except relaxing all day long.''

The couple's daughter North West is set to celebrate her first birthday next Sunday (15.06.14).
