The drummer had previously revealed it’s his dream to call his son Rocky Thirteen after Rocky George from hardcore metal band Suicidal Tendencies and boxer Rocky Balboa (Sylvester Stallone) from the ‘Rocky’ and ‘Creed’ movies.
Speaking to Toby Morse on the One Life One Chance podcast, he slipped up: “There was a benefit in Hawaii that we were gonna do, but it’s the week that Rocky’s due.”
The host then said: “Rocky Thirteen Barker,” to which Barker repeated: “Rocky Thirteen Barker!”
The drummer - who also recently revealed that their baby was due around October 31 - then joked: “He’s gonna come out of my wife’s vagina like doing front kicks and push-ups.”
Kardashian announced that she was expecting in June by holding up a sign reading “Travis I’m Pregnant” at one of her husband’s concerts in LA.
After seeing his wife’s message, Barker, 47, jumped down off the stage and made his way towards her for a celebratory kiss.
They later shared some video footage of the moment in a joint Instagram post.
Kardashian’s younger sisters Kim, 43, and Khloe, 39, took to social media themselves to share their congratulatory messages to the couple.
Kim wrote on Instagram: “Congrats!!! We’re having a Kravis baby!!!” whilst Khloe said: “Congratulations my cuties!!! I love you and baby sooooo much.”
Meanwhile, an insider claimed that the news was beyond anything they had dreamed of and that the pregnancy was a “complete miracle”.
The source told Entertainment Tonight: “Kourtney and Travis are on cloud nine. This pregnancy is beyond Kourtney’s wildest dreams. Kourtney and Travis feel like this is one of the most magical things to happen to them and a complete miracle. They are so thrilled and can’t wait to experience this pregnancy together, bring a baby into the world as a unit, and expand and grow their families.”
