The blonde boutique owner is seen in preview pictures appearing to break down in tears as she tells sister Billie Faiers and friends Jessica Wright and James 'Arg' Argent that she needs a break from the programme.
Dressed in a sparkling gown for Jess and Ricky Rayment's prince and princess-themed finale party, the reality star looks visibly upset at the thought of leaving TOWIE behind for now.
Thankfully for fans, her exit isn't permanent, as Sam is expected to return to The Only Way Is Essex when pregnant sister Billie gives birth.
A source told Reveal: " Sam has decided to leave TOWIE at the end of this series, however this won't be the last we see of her.
"The plan is for Sam to return for a few episodes in the next series when Billie has the baby. Billie wants to stay put and the door will always be left open for Sam for future appearances."
Sam has been rather in the background during this series of TOWIE, probably because she's been focusing on her health and well-being after being diagnosed with the inflammatory bowel disease Crohn's.
She's yet to explain why she needs a break from TOWIE but perhaps it's to continue on her road to recovery. It's also been suggested that she wants to work on her relationship with co-star Joey Essex away from the cameras.
Sam and Joey appeared to confirm they're back together this week by sharing an Instagram photo of themelves cuddling up in bed together.
TOWIE's season finale episode airs Wednesday, 2 April at 10pm on ITV2, but the show will return to our screens for a further two series this year.
