You'll recognise her from your fave shows like Gossip Girl, Supernatural and Arrow (to name a few!) and soon you'll be seeing Katie Cassidy all dolled up in white.
The 30-year-old actress took to Instagram to share the news that her bae, Matthew Rodgers has proposed.
“I can’t wait to spend forever with you my darling!! I’m the luckiest girl in the whole world. I ❤️ YOU to the moon and back @mattyice432 Thank you for a magical evening I will forever remember,” Cassidy wrote alongside the cute AF pic.
Check. Out. That. ROCK!
She also shared a poolside pic with her new fiance where the pair jumped into a pool.
Katie currently plays Dinah Laurel Lance in The CW's superhero series, Arrow.
Congrats to the happy couple!
