And Sarah-Louise Platt will finally lock lips with bad boy Callum Logan during April 13's Coronation Street double bill.

The single mum, played by Tina O'Brien, can't resist the drug dealer's charms any longer and the pair tear each other's clothes off inside the Platt family home.

Passionate embrace: Sarah-Louise Platt (Tina O'Brien) shares a kiss with Callum Logan (Sean Ward) in Coronation Street scenes airing on Monday April 13

Just as things are starting to heat up, with Callum (Sean Ward) removing his shirt in the process, their moment of passion is interrupted.

All of a sudden, David Platt arrives home, with his step-son Max and niece Bethany in tow.

David and Callum have been battling for custody of Max since Kylie Platt left the Street, so finding his sister in bed with his rival isn't going to go down well.

Paula Lane, who plays David's estranged wife Kylie, recently confirmed she had resumed filming for the ITV soap, so tension between David and Max's biological father Calum is expected to reach an all-time high in coming weeks.

Kylie was last seen when David kicked her out of the Platt household after learning that her ex Callum had been supplying her with drugs.

Meanwhile, actress Tina is loving every minute of her Corrie return, especially Sarah-Lou's surprising choice of love interest.

'I'm sure people think it's funny that the second she walks in, she hooks up with the guy who will cause most problems with the family', the 31-year-old star recently told Digital Spy.

'To begin with she isn't interested in Callum at all. It's only because David really gives her a hard time that it almost pushes her towards Callum. 

Also making her show debut is Lucy Fallon, 19, who is playing young mum Sarah's 14-year-old daughter.
