Cameron Diaz and Benji Madden briefly left their new baby bubble to celebrate a good friend's milestone birthday.
On Saturday, the couple stepped out in Los Angeles for Rob Lowe's 60th birthday party, which also saw attendance from fellow celebrities like Robert Downey Jr., Gwyneth Paltrow, Katy Perry, Orlando Bloom, Adam Levine, Behati Prinsloo, Ellen DeGeneres, Portia de Rossi, as well as the West Wing actor's wife Sheryl Berkoff and their sons John Owen and Matthew.
The Charlie's Angels actress, 51, and the Good Charlotte singer, 45, were spotted heading to the star-studded party both coordinating in casual black outfits.
Their outing came a day after the couple, who tied the knot in 2015, made the surprise announcement that they had welcomed their second child together, a son named Cardinal. They are also parents to daughter Raddix, who is four years old.
Benji made the announcement in a joint Instagram post with his wife, sharing a photo of an abstract drawing featuring colorful brush strokes, a pink rose, a sketch of a young boy, and the words: "A little bird whispered to me," written in a gothic font.
Their announcement first read: "We are blessed and excited to announce the birth of our son, Cardinal Madden."
The pair continued: "He is awesome and we are all so happy he is here!" before noting: "For the kids safety and privacy we won't be posting any pictures – but he's really cute," next to a smiley face.
