Dan is currently visiting TOWIE's favourite holiday destination and was seen earlier this week speaking to a bikini-clad girl during a boat party.
At one point, the unnamed party-goer and Dan leaned their heads in very close together - presumably because of the loud music - however the scene did raise a few eyebrows.
EastEnders star Jacqueline insists she has nothing to worry about though, and has taken to Twitter to vent her feelings about the situation.
Last night, the actress simply told her followers: "People love to make something out of nothing."
Jacqueline's fans were quick to reply, coming down on her side. One said: "Only you know the truth, Jac :) Hope you are well xx." Another added: "Like being in a damn soap opera, eh?"
Dan and Jacqueline briefly dated last year but split after it emerged he was expecting a baby with his ex-girlfriend, his beloved son Teddy.
In June, however, Dan and Jacqueline appeared to be back on and they are now looking happier than ever.
Last month, Dan admitted on TOWIE that he is "in love" after his co-stars grilled him about his soap star girlfriend.
Well, the feeling is clearly mutual!
