Currently putting her feet up at home, Jacqueline - who recently gave birth to daughter Ella - won't be joining the rest of the cast on set for this evening's episode.
But letting her friends know she is thinking of them all, the 22-year-old took to Twitter to send her luck and share her excitement ahead of EastEnders' big revelation.
She tweeted: "So we finally find out who killed Lucy tonight?? Oo I am too excited!! #EELive good luck everyone at @bbceastenders."
This week the EastEnders cast have been taking part in live scenes as part of the soap's 30th anniversary celebrations. And finally, after months of waiting, viewers will get to find out who is the culprit behind Lucy Beale's murder!
On Tuesday night, Jake Wood (Max Branning) sent fans into a frenzy after they thought he accidentally dropped a bombshell about Lucy's killer. He was seen saying to daughter Abi: "[Lauren] knows... that you killed Lucy."
Clearing up the confusion, Jake later tweeted he HAD meant to accuse Abi - although viewers saw in last night's episode the teen admitted she wasn't the culprit.
Instead, viewers saw Lauren Branning (played by Jacqueline) tell Peter Beale his sister was killed at home. And in true Albert Square fashion, when Peter confronted his dad Ian and wife Jane, the EastEnders theme tune kicked in leaving fans hanging on!
Tonight though, ALL will be revealed in a flashback episode that will see the return of Hetti Bywater (Lucy Beale) and fans will finally get to see how she met her fate.
