Kim Kardashian and Kanye West have embarked on their ''official honeymoon'' to Mexico.

The couple - who recently wed in a lavish ceremony in Florence, Italy - were believed to have spent their honeymoon in Ireland and Prague, but it has now been revealed they have jetted south of the border to continue their celebrations in Punta Mita.

Mr. and Mrs. West - who are staying at a private residence at the Mexican beachfront village - are also celebrating the 'Yeezus' rapper's 37th birthday during the trip.

Earlier this week, the 'Keeping Up with the Kardashians' star took to her Instagram account to wish her husband, the father of her 11-month-old daughter North, a special day.

She wrote: ''Happy Birthday to my husband and best friend in the entire world! You have changed my life in more ways than you know.

''The way you look at life inspires me! I love you so much!!!!''

Meanwhile, it has been suggested the pair may be looking to expand their brood while enjoying their romantic holiday.

A source told Us Weekly: ''I think Kim will definitely have another baby soon - she wants to.''

Speaking in an interview with Ryan Seacrest earlier this year, the brunette beauty confessed she wanted more kids but said she couldn't ''do more than three tops''.
