Rumours of a reconciliation were sparked after it was revealed Tristan and Khloe have been quarantining and parenting their daughter together amid the pandemic.
According to a source for People magazine, the two are "clearly enjoying each other's company".
"The lockdown made them closer.
"Tristan has been on his best behaviour. Khloe is definitely charmed by him. If he is able to keep things up, it's very possible that Khloe would get back with him."
The insider added that Khloe wasn't dating anyone else.
"They hadn't spent this much time together since they lived in Cleveland. They have had an amazing spring with True in L.A."
Khloe and Tristan split shortly after True's birth in 2018 following the NBA star's affairs with several women.
They have remained cordial for their daughter's sake.
