A little after one year of marriage, Kourtney Kardashian and Travis Barker are having their first child together. Kardashian surprised her husband by paying tribute to one of his most popular songs at a Blink-182 concert in Los Angeles. In the “All the Small Things†music video, a woman holds up a poster with the words “Travis I’m pregnant†in a crowd, similar to what Kardashian did Friday night. “Hey Travisssssss!†“Oh, he’s doing the dirty!†tease his bandmates Mark Hoppus and Tom DeLonge on stage while the camera was on Kardashian as she showed the sign off. Upon hearing the news, Barker got down from the stage to give his beloved some of their infamous PDA. Throughout the three seasons of The Kardashians, the couple has documented their battle with infertility and their desire to have a child together — Kardashian has three children with her ex Scott Disick and Barker has two with his ex-wife Shanna Moakler. Poosh pre-natal vitamins, anyone?
