Khloé Kardashian and Lamar Odom are seeking couples counselling.

The couple, whose four-year marriage has been rocked by allegations he cheated on her and has been battling an addiction to crack cocaine, have reportedly been visiting a prominent Beverly Hills therapist in a bid to iron out their problems.

A source told Us Weekly magazine: ''It was very emotional; they spoke about all of their issues. Khloé still loves and cares about him, but healing will take a long time.''

A source also revealed that Lamar, 34, is ''doing so much better'' as he is ''clean and has gained 20 pounds.''

The couple put on a united front for the first time in months at Khloé's mother Kris Jenner's 58th birthday party last week.

An insider told E! News: ''It was just close family and friends. Lamar and Khloé are actually getting on very well and were couple-y together. It was very intimate and everyone was really pleased to spend time with them.''

The 'Keeping Up with the Kardashians' star, 29, is preparing to go away for a promotional tour to the U.K., Dubai and Australia and is planning to use the time to get perspective on her life, marriage and feelings towards Lamar.

It was previously reported that the brunette beauty had signed her divorce papers but hadn't filed them because she was desperate to save her marriage.

An insider recently said: ''At one time it seemed like a reconciliation was impossible and divorce was inevitable. Things may have turned a corner.''
