Ryan Reynolds and Blake Lively have announced the name of their fourth child, born in 2023: Olin. The couple, who also share daughters James, Inez, and Betty, made the reveal during the premiere of Reynolds' film *Deadpool & Wolverine* on July 22. Reynolds expressed his gratitude to Blake and their children from the stage, humorously noting that he hoped the movie would be the most traumatic thing their kids would experience. The name reveal has been highly anticipated, with Reynolds joking earlier this year about waiting for Taylor Swift to disclose it. While the sex of the baby remains undisclosed, Reynolds, who has previously spoken about the joys of being a "girl dad," is excited about expanding their family. The couple, married since 2012, continues to enjoy their growing family dynamics.
