Kim Kardashian and Kris Humphries are still talking.

The 31-year-old beauty - who filed for divorce from Kris after just 72 days of marriage on Monday - have been in touch since she has been in Australia on a business trip, which she has now cut short.

A source told RadarOnline.com: "Kim and Kris have spoken on the telephone, and are frequently exchanging text messages on their BlackBerrys.

"Kim is absolutely numb and was truly surprised and shocked at the backlash she has gotten since she decided to file for divorce."

However, it is not likely the pair will be reconciling because they are "completely different people".

The source added: "It's highly unlikely that Kim would want to get back together with Kris. Kris is in Minnesota, and the more time that goes on, Kim clearly sees that they are just two completely different people, that never should have gotten married."

Kim had been due to attend a horse racing event in Australia but has now decided to head back to her native Los Angeles.

Her representative told the NY Daily News: "During this very difficult time, she felt it'd be best to return home to close friends and family."
