On April Fools' Day, Gwen Stefani [1] took to Instagram with a too-real joke. "It's a girl," she captioned a picture of an ultrasound [2]. Gwen appeared on Good Morning America shortly thereafter, and her glowing smile was enough to convince us of one thing: she's probably pulling one over. That said, it wouldn't necessarily be a surprise if Gwen was expecting a baby with Blake Shelton. Things have heated up pretty quickly between the couple since they started dating in November [3]. In the short time since, they've had some pretty epic PDA [4], spent the holidays together [5], and even attended a wedding as each other's date [6]! And yet, we're still going to go ahead and say a baby must be pretty far off. Keep reading to see the snap in question, then check out the other pics from Gwen's Friday outing.
