The actress is reprising her role as Amira Shah once again before her on-screen ex-partner Syed Masood makes his departure from the show.
Kalidas hinted at Amira's return on Twitter last week, telling fans: "The heels are back and I'm not talking about mine."
An EastEnders spokesperson confirmed the news to Digital Spy today (September 11), explaining that Amira will be back on screen for a couple of episodes.
The reasons for Amira's return have yet to be revealed, but show bosses have promised plenty more drama for the Masoods in the build-up to Syed's exit.
Amira was last seen in Walford in March, when she left the area after finally realising that Syed would never love her.
Marc Elliott and John Partridge, who play Syed and his lover Christian, announced their EastEnders exits last week and will depart screens in November.
