EastEnders fans will know there's always been something between Tina and Sonia, but their respective partners have always got in the way.
But now they're both single, there's no stopping them!
A source told the Mirror: "They finally give into the tension that has been building and kiss.
"There has been a spark for a while but it hasn't amounted to anything."
And it looks like this kiss might not be a one-off for the unlucky-in-love pair, with the insider adding: "This could be the start of something beautiful."
This isn't the first time Sonia and Tina has kissed – last year they had a moment, despite Tina being in a relationship with Tosh.
Regular viewers of the soap will know that Sonia has experimented with her sexuality in the past.
Back in 2005, the nurse shared a kiss with co-worker Naomi Julien.
These scenes will air on 17 March on BBC One at 7.30pm.
