Blake Lively
Fans of the original Gossip Girl will remember that Penn Badgley's Dan Humphrey and Blake Lively's Serena van der Woodson had an off-and-on-again relationship to rival Friends' Ross and Rachel. However, much to the delight of fans, their chemistry spilt over into real-life and the two actors began dating in 2007, although they initially kept it a secret.

Sadly though, things didn't work out and they parted ways in 2010 but continued to play their respective roles on the show. Speaking about their relationship to Elle in 2013, Penn descried it as "good and bad" and a "learning experience".
The same year they split, Blake met her now-husband Ryan Reynolds on the set of superhero flick The Green Lantern. The couple wed in 2012 and are now parents to three young daughters.

Zoe Kravitz
After his separation from Blake, Penn dated Batman actress Zoe Kravitz from 2011 to 2013. It's now known how the couple met, although Penn became close to Zoe's famous father, Lenny Kravitz, during the course of their relationship. He told US Weekly: "We get along, we talk music. [Lenny] took me to Harlem to see this little jazz show in the back of a church."

Their break-up was reported to have been amicable and due to conflicting schedules. Big Little Lies star Zoe went on to embark on a relationship with Channing Tatum following his split from Jessie J.
Domino Kirke
Penn met his wife, Domino Kirke, a singer and doula to A-listers like Amy Schumer, in 2014. The pair tied the knot three years later in early 2017 at a simple courthouse ceremony. Last August, the happy couple welcomed their first child together, a son named James. However, during their relationship, the couple have suffered two devastating miscarriages. Meanwhile, Domino is also a doting mum to her ten-year-old son, Cassius, whom she shares with her ex-partner Morgan O'Kane.

Domino has previously opened up about her relationship with the A-lister. Speaking to Hey Mama, she revealed that when she first met Penn, she didn't expect their relationship to become serious.
"I was sort of getting used to being a single mom, maybe a little too used to it," she said. "I had a really good thing with my kid and we were like this little team. Penn and I were dating, but it wasn't nearly as serious as it is now, of course. I didn't think marriage was in the cards for us.
Meanwhile, Penn himself has said that becoming a father has changed his approach to playing serial killer Joe in the Netflix series, which debuted its third season on Friday 15 October.

He told Access: "The funny thing is I was curious what my new fatherhood, how that would influence my experience with Joe and acting with him, and sometimes it was almost not helpful because I was having such a light and joyful experience — still am — and Joe is so petrified."
He continued: "He's so scared, and of course I can identify with the fear, but he's just so morbid in his obsessive, sort of like self-preservation, primal instinct that sometimes I almost found it harder as a result."
