Roxy panics when Harlow discovers the truth about her hook-up with Mark on Neighbours. Will Harlow spill the beans to Mark's ex, Elly?

Roxy Willis (played by Zima Anderson) and Mark Brennan (Scott McGregor) have been trying to keep things on the down low since their secret hook-up on Neighbours (opens in new tab).

But it's getting trickier to keep the secret from their friends and family since the naughty neighbours can't seem to keep their hands off each other!

However, in today's episode of Neighbours (opens in new tab), Roxy's housemate Harlow Robinson (Jemma Donovan) becomes suspicious when she notices how upbeat bar co-owner Roxy is, despite the fact she and business partner Leo Tanaka (Tim Kano) could soon lose the Back Lane Bar after Leo was ripped-off by conwoman Carly Abernethy.

So when Harlow catches Roxy exchanging sexy texts with Mark, she can't believe her luck. Now she has some dirt on her arch-rival, as there's certainly been no love lost between these gals since Harlow first arrived in Erinsborough and moved into Number 22!

Roxy begins to panic when Mark's ex, Elly Conway (Jodi Anasta) enters Harold's Cafe, and Harlow threatens to spill the beans...

Will news of Roxy and Mark's secret fling soon spread on the Ramsay Street grapevine?

Elsewhere, Paul Robinson (Stefan Dennis) is on the defensive after his showdown with his ex-wife Lyn Scully (Janet Andrewartha).

Paul is relieved when fiancee Terese Willis (Rebekah Elmaloglou) reminds him that in just a few weeks they will be married and honeymooning in Europe, away from his meddling ex-wives.

But it seems there's more trouble to come when Lyn cryptically hints to Sheila Canning (Colette Mann) that Paul's luck is about to run out!

Hmm, what does Lyn know that we don't?

Neighbours continues weekdays at 1:45pm and 5:30pm on Channel 5
