The reality star was pictured wiping tears from her eyes as she spoke with pals Georgia Kousoulou and Lewis Bloor while shooting a scene for the ITVBe show in Billericay.
We wonder what's wrong with poor Lydia?!
Perhaps it's something to do with on-off boyfriend James 'Arg' Argent? He's had a difficult time lately after checking into rehab before Christmas, and it still hasn't been confirmed whether he will be rejoining the show.
Lydia has said arguments with Arg were her "low" of the last series, but adding: "It has been so nice that instead of cooling things off on bad terms, for once we still remain very close and amazing friends and I hope this continues."
The new series of TOWIE begins on Sunday, 22 February at 10pm on ITVBe.
Lydia and a bunch of other co-stars flew to Tenerife earlier this month to film some scenes for the opening episode and Lydia's teased there will be fireworks aplenty.
"We renamed it Tener-grief! There has never been so many arguments on one holiday. There was so much commotion, tears and tantrums," she said.
"I think it happens when girls get together. There's a lot of opinionated and big characters among the cast and it ended up getting catty. Tensions were definitely rising.
"I actually feel as though we've peaked, where is it going to go now? The first episode is going to be so explosive!"
