After rumours they spent weeks barely seeing each other and living separately, the couple came together yesterday evening (29 October) in support of Kanye at the Los Angeles date of his current Yeezus tour and were both pictured alongside the rest of the Kardashian clan, including Rob, Kim and Kris Jenner, in LA's Staples Centre.
Khloe was seen wearing a Yeezus tour T-shirt and black leggings, while Lamar was dressed similarly in all black and a snapback cap.
Apparently the couple looked very happy and remained next to one another throughout the show
This is also said to be the latest in a string of meetings Khloe and Lamar have had lately, in a bid to save their marriage.
A source told E! News: "[Khloe] still loves him, but they're still not back together...[Lamar] wants to prove to her that he is the same person she married."
The two stars - who have been married for four years - are thought to be going through a rocky patch in their relationship, following numerous allegations that Lamar cheated on Khloe and that he was harbouring drug issues. Lamar hasn't commented.
Although they continue to live apart, Khloe and Lamar have not confirmed rumours of a divorce and instead have each spoken out about how much love means to them in respective Twitter messages.
A few weeks ago, Khloe was seen tweeting: "Promise me you'll always remember: you're braver than you believe. I am brave because of you. The love you gave made me brave. All we need is love #KKO"
Meanwhile, Lamar has come to the defence of the Kardashians after his estranged father Joe accused the reality TV stars of ruining his son's reputation.
With reference to Khloe and her family, he tweeted: "He disrespecting the ONLY FAMILY that has loved me without expecting anything in return. They are the ONLY ones that have been here consistently for me during this dark time."
It is still unclear as to whether Khloe and Lamar will be reuniting, as the source also admitted that they aren't sure if Khloe can move forward with her basketball player hubby.
But for now, the pair do look as though they are trying to get back on track.
Also at the Kanye West concert in LA this week was new-mum Fergie, who grabbed a quick snap with Khloe and fellow first-time mum Kim.
