(Cover) - EN Showbiz - Khlo Kardashian and Lamar Odom celebrated Memorial Day weekend by going on a romantic break to focus on starting a family.

The pair, who married in September 2009, stayed at the Montage Resort & Spa in Laguna Beach, California to finally enjoy the honeymoon they hadn't taken after tying the knot. However, sources close to the couple have revealed the reason they took time out of their busy schedules was to spend time focusing on starting their family.

Sources have also revealed that Khlo, who's tried to get pregnant for a year, has decided to look into fertility treatments.

"She told me she's been working with a doctor and a team of people to help her get pregnant. She recently stepped things up and began exploring new methods," a source close to the family told Life & Style.

"She's asked about every possible way to help her infertility problems, like trying artificial insemination and in vitro fertilization," a friend of Khlo's confirms. "She really wants to get pregnant by the end of the year."

Lamar already has three children with ex-girlfriend Liza Morales. The 31-year-old NBA star is said to be keen to welcome a child with his reality TV star wife but isn't putting any pressure on her.

"He's being extremely supportive and is willing to do whatever it takes," an insider revealed "But at the end of the day, he just wants Khlo to be happy." (C) Cover Media
