It's no secret that the reality stars haven't seen eye-to-eye after previously clashing over Charlie Sims, but last night they were happily singing together as they went head-to-head with the Made In Chelsea girls.
Jasmin and Ferne attended the Jog On To Cancer charity fundraising event held at Kensington Roof Gardens in London on Wednesday (9 April).
And in no time at all, the duo were singing along to Gabrielle's 2001 hit 'Out Of Reach' with MIC's Cheska Hull and Fran Newman-Young.
Jasmin posted two videos of the pair singing on her Instagram account - and it sounds like they had a pretty good night!
Fans of TOWIE will remember that in series 10 last year, Ferne and Jasmin were at loggerheads over Charlie.
Jasmin got close to Charlie in Las Vegas, while he was in the middle of a bitter split from Ferne, and the pair exchanged some very harsh words. Although now it seems that it's all water under the bridge!
After the charity event last night, Jasmin was seen leaving the venue with co-star Tom Pearce, and looked happy to put her recent drama with Dan Osborne behind her.
In the last series, Jasmin revealed her true feelings for Dan, which led to them going out on a date.
Things seemed to be going well, but the series finale saw Jasmin upset over Dan's apparent mixed messages, after he had earlier told Georgia Kousoulou that he didn't see Jasmin ever being his girlfriend.
Dan said: "I don't want you to feel led on and ruin our relationship."
But it was too late for Jasmin, who told him, "You have ruined our friendship. I thought you were a genuine boy."
