Khloe Kardashian's famous family have reportedly "forgiven" Tristan Thompson for his alleged cheating scandal.

The 33-year-old reality star had a stressful time after the NBA star was caught seemingly getting close to another woman just days before Khloe gave birth to their daughter True back in April, and the ordeal caused a rift between Tristan and Khloe's famous family.

However, the 'Keeping Up with the Kardashians' star patched up her romance with Tristan, 28, and it has now been claimed that her family - including mother Kris Jenner, sisters Kim Kardashian West and Kourtney Kardashian, half-sister Kendall and Kylie Jenner, and brother Rob Kardashian - have also moved past the drama.

A source said: "Everyone is back on board - friends, family and Khloe have all forgiven him and are giving him this second chance - and so far it's been working for them. [Khloe's family] is all about forgiveness, and now it's up to him to prove himself."

The 'Revenge Body' star's family were "concerned" when the scandal first broke over two months ago, but Khloe is believed to be "so happy" that she decided to stay in Cleveland with Tristan to work on their romance.

The insider added: "Her family was obviously very concerned when the scandal broke and they wanted her to come home, [but] she decided to stay and is so happy she did. She loved her time in Cleveland and believes it was essential to their relationship to be together as a family unit during that time. Those are important months as a parent and she is grateful they experienced that as a team.

"True is Khloe's absolute world. She loves being a mother and True is her pride and joy."

Currently, Khloe, Tristan, and True are all back in Khloe's hometown of Los Angeles visiting her family, and talks of moving back to the Californian city are reportedly ongoing.

The source told 'Entertainment Tonight': "[Tristan] has a home in L.A. too, but the plan is to live together as a family at Khloe's home as they continue to work on their relationship."
