Hold onto your corsets, "Bridgerton" fans, because things are getting steamy – and not just on screen. The show's stars have been making headlines for their undeniable chemistry, but one pairing in particular has got tongues wagging: Nicola Coughlan and Luke Thompson.

While the "Polin" romance (Penelope and Colin) is heating up on-screen, it seems like the off-screen chemistry between Coughlan and her co-star, Thompson (who plays Benedict Bridgerton), is hotter than ever.

She's seen wrapping her arms around Thompson's neck, her head resting on his shoulder as they chat, a playful grin on her face.

She even leans in for a prolonged hug, her arms tightly encircling him.

"Oh, my God! They're practically joined at the hip!" one fan commented on the video. "Penelope and Benedict are giving me major 'couple vibes'!"
