The reality TV star, 29, looked stunning when she arrived at BBC studios on Saturday (4 October) to watch her younger sibling and former co-star Mark dance his little socks off with professional partner Karen Hauer.
Jess wowed in a pink animal print mini dress from her own range, With Love Jessica, which showed off her perfectly tanned and toned legs. Gorgeous!
She, mum Carol and dad Mark Snr went to see Mark perform the American Smooth, which earned the I'm A Celebrity... hunk 27 out of a possible 40. Not bad for a beginner!
After his dance, Mark admitted: "I am a bit of softie. Second week in a row I feel like crying again."
While mean judge Craig Revel Horwood described Mark's arm movements as "terrible", Len Goodman was far more complimentary, saying: "I don't know about The Only Way Is Essex. For you, the only way is onwards and upwards!"
After recovering from his energetic routine, Mark took to Twitter to thank fans for their support.
He wrote: "Loved tonight so much and it was so overwhelming to have everyone's amazing support. Also, it was amazing to have mum, sis, dad and michelle there."
He also added: "So proud of my amazing dance partner @karen_hauer for being so patient with me and getting us through another dance x."
Mark's fiancée Michelle Keegan was also in the audience. Before his dance, she urged her Twitter fans to vote for him.
She begged: "Everyone PLEASE vote for @MarkWright_ text 6225205 #strictlycomedancing.
"Let's all get behind him #teammark."
With such huge support behind him, we have a sneaky feeling Mark won't be going anywhere for a little while...
