The headline only mentions Brad Pitt as a source for a rumor that the Jolie-Pitt clan will be adding another member, but the picture on the cover is of BrAngelina, so this story gets a label mentioning both of them. With these two, it may not be a Bun In The Oven Alert™ per se, but that's the only label I have that fits.
It should also be noted that a new addition to the Jolie-Pitt clan is a rumor as popular as the Kardashian pregnancy stories, and we haven't had one of those in at least two years.
