"Me and Seth," she captioned the snaps. Making it clear that Nicola was indeed talking about him, Brooklyn replied: "Love you baby xxx me and you forever," followed by a red heart emoji.
Many fans were quick to question, "Who is Seth?", while others queried whether Nicola affectionately referred to Brooklyn as "Seth" because he reminds her of Seth Cohen – a character played by Adam Brody on TV drama The O.C, which ran from 2003 until 2007.
"Who the [expletive] is Seth?" commented one confused follower. Another said: "Is this an OC TV show reference?" A third added: "Is he your Seth Cohen?"

The couple, who got engaged last July, recently had matching butterfly tattoos inspired by a picture Brooklyn took while watching Nicola work on new drama Lola James.
Brooklyn got two large butterflies tattooed onto his arm, while Nicola had a small one inked onto her chest.
Earlier this month, the couple even had matching gold necklaces made using their wisdom teeth.
