Whitney Dean
EastEnders' Whitney Dean cheats on Tyler Moon with Joey Branning.
The feisty brunette - played by Shona McGarty - does the dirty on husband-to-be Tyler (Tony Discipline) just weeks before their big day when she jumps into bed with the hunky lothario Joey (David Witts) after a heavy night out on the town.
In one of the most raunchiest scenes ever aired on the soap, viewers will see the saucy pair head back to Joey's house where they rip each other's clothes off and get it on.
However, Whitney is hit with guilt after waking up in his bed and begs the stud - who has previously dated his cousin Lauren Branning (Jacqueline Jossa) and her pal Lucy Beale (Hetti Bywater) - to keep quiet about what has happened.
An insider told the Daily Star newspaper: "Whitney will feel terrible after she cheats on Tyler with Joey.
"She loves Tyler and doesn't know why she did what she did.
"Whitney and Joey are two of the soap's most popular young characters and the fallout will be huge if this gets out.
"Tyler and Whitney's relationship has always been a bit up and down. Whitney is really going to struggle with her guilt.
"All she wants to do is come clean. It's going to be an emotional time for Whitney."
Meanwhile, Tamwar Masood - played by Himesh Patel - will take centre stage in his own four-part online spin-off, 'The Tamwar Tales - The Life of an Assistant Market Inspector', which will go live on July 25.
An 'EastEnders' spokesperson explained: "For the first time ever, we are able to hear what Tamwar is really thinking as he endures all that life throws at him - the excuses, teasing and daily hassles from his regular stallholders."
Himesh added: "It was really fun working on the four shorts. It was like taking a character that we know and putting him in a different genre. Viewers who are a fan of Tamwar will finally get a look inside his head."
