Out holidaying on the White Isle at the same time as TOWIE is filming, the former Celebrity Big Brother star joined up with the Essex gang for a night on the tiles on Sunday (21 September).
Looking gorgeous in a slinky black dress, Casey effortlessly blended into the TOWIE cast as they posed for photos outside Ocean Beach Club Ibiza.
Casey is best friends with TOWIE star Danielle Armstrong, which is why she was out partying with the gang.
A source, however, tells Reveal that Casey's trip to Ibiza is all about pleasure – not work! – and she won't be appearing in the new series of TOWIE. Boo!
Joining Casey and Danielle on their very glam night out were Danielle's boyfriend James Lock, Georgia Kousoulou, Jasmin Walia and last year's newcomer, Vas J. Morgan.
Although not appearing in the new series of TOWIE, there's no doubt Casey has been firmly in the mix since arriving in Ibiza!
She's tweeted pictures of herself partying with the TOWIE girls at their villa, sleeping off a hard night's partying with Dan Osborne (lucky thing!) and enjoying dinner with the group.
TOWIE's brand new series will air next month on new channel ITVBe.
