Keri Russell and Matthew Rhys have welcomed their first child.

Woah, guys I think you’re going to need to sit down for this one.

Because, you’ll never guess, a celebrity couple have had a baby and not signed an exclusive picture deal with a tabloid or celebrated the birth across their social media. Yep, they are a Hollywood anomaly.

Our favourite ’00s angst-y college teen, Felicity, played by Keri Russell has just welcomed a child with fellow actor, Matthew Rhys.

You can watch the theme from Felicity below for a good dose of nostalgia. Post continues after video.

The pair, who co-star in the show The Americans together, have been papped carrying their newborn just hours after the announcement of the birth on Monday.

People Magazine reported that a source had confirmed the 40-year-old and her partner of three years welcomed their first child together at the beginning of May. News broke Russell was pregnant back in January when a separate source told People that, “Russell and Rhys were ‘thrilled’ about the upcoming addition to their family.”

This is Russell's third child. She is already mum to River, 8, and Willa, 4, with her ex-husband Shane Deary. It is Rhys who has just become a first-time dad.

In an interview with Parade, Russell spoke of being a mum in Hollywood, "You instantly become less selfish. You can't be the biggest person in the world anymore -- they are. It really grounds you."

While there is no word yet on the sex or name of the child, a big congratulations are in order for the happy couple.
