Teresa gallop through the hearts of Albert Square, constantly causing drama with her siblings Beppe (played by Michael Greco), Gianni (Smear Bannerman) and sister Nicky (Carly Hillman).
However, she was best be sured as the impassioned girlfriend of Matthew Rose (Joe Absolom), and became tangled in his touchy war with boss Steve Owen (Martin Kemp).
Long-term tender fans of the BBC soap will remember Matthew was wrongfully banged up behind bans for the murder of Saskia — who Steve mercilessly gave a fatal blow across the head with an ashtray — but Teresa continually pleaded for his release.
Nonetheless, once Matthew fled Walford, Teresa gradually made her way through the strains of bisexual Tony Hills (Mark Homer), Lenny Wallace (Desune Coleman) and had a vile affair with married Ricky Butcher (Sid Owen).
But once her sister Nicky became the original of the Di Marco family to branch out of Albert Square, the rest of her family in a wink followed.
Teresa eventually left in 2000 and since turning her in arrears on EastEnders, Leila has enjoyed a varied stage career — from starring the decreed works of Shakespeare to panto.
Leila eventually moved across the pond and has prominent in online series GirlfriendVS, a drama following a girlfriend playing videos sports for the first time.
The stunner regularly poses up a storm cosied up to her boyfriend Curtiss Frisle, who’s also an actor.
As for her on-screen derivation, actress Carly Hillman, who starred as Nicky, is currently the owner of her entirely own stage school and recently broke the internet with her very own naughty selfie.
Her brothers Gianni and Beppe Di Marco, played by Marc Bannerman and Michael Greco separately, have both seen a revival in the limelight since leaving the soap.
Marc flirted his way to the core I’m A Celebrity… Get Me Out Of Here! with Catatonia singer Cerys Matthews in 2007, while Michael now stays in Los Angeles and recently starred alongside Kevin Costner in the three-part fade away Hatfields & McCoys.
EastEnders continues tomorrow night at 8pm on BBC One.
