Khloe Kardashian felt as though Kim Kardashian and Kanye West had been ''married in another lifetime''.

The 'Keeping up with the Kardashians' star, who claims she convinced her sister to start dating the rapper because she'd always known he was in love with her, has confessed she was blown away by the calmness and serenity of their Italian wedding last month.

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

''I have always believed these two are soul mates.''

Kim and Kanye - who have 11-month-old daughter North together - are currently enjoying their ''second honeymoon'' in Mexico after spending the days after their wedding in Ireland and Prague.

An insider revealed: ''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.''
