Well, here’s a surprise debunked: Chris Martin and Dakota Johnson are not having a baby together after all, despite reports from TMZ that the couple, who have been together a year, announced the news at what appeared to be a gender reveal party Sunday. TMZ had reported that footage of balloons being released from Martin’s house seemingly announced they’re expecting a boy. Not so, per Johnson's rep.

Johnson's rep told Us Weekly that Johnson is not pregnant; the party was a birthday celebration. Johnson’s parents Melanie Griffith and Don Johnson were among the guests, as were Sean Penn and Julia Roberts.

Johnson and Martin have been dating about a year.

This article has been updated to include Johnson's response to TMZ's report.
