The EastEnders actress wowed in a cute white dress while walking the pink carpet The Rise nightclub in London's Leicester Square on Tuesday (9 September).
There was absolutely no sign of any baby bump in her tight-fitting frock, which she covered with a white furry coat to keep the chill away.
Soap star Jacqueline is expecting her first child with Dan. They announced their baby news last month.
Jacqueline was on hand last night to cheer on TOWIE star beau Dan, who was making his debut on The Dreamboys' Fit and Famous Tour.
And clearly Jac was impressed!
The mum-to-be couldn't resist tweeting during the night: "Wooo!! Take it off!!!"
We're pretty sure she wasn't the only one in the audience screaming that at gorgeous Dan and his equally hot stripper colleagues!
Jacqueline later said: "I've lost my voice. Woo! Loved it! @TheDreamboys @DannyO. Sexyy!!!"
Reveal chatted with Dan shortly before he made his stripping stage debut and, surprisingly, he admitted he wasn't that nervous about baring all for the crowds.
"Believe me, it's not the first time I've stripped off!" he joked. "Well, I guess on stage it is. I feel alright about it, they don't strip completely off anyway... it's just like being in your boxers in front of everyone. That's not too bad, right?"
If you fancy catching Dan and the boys in action, make sure you get tickets for one of their six remaining shows across the UK. Get your tickets and full details here.
