Suki Waterhouse and Robert Pattinson have been romantically linked since 2018.
Recent photos of the couple on a hike in Los Angeles show Suki wearing a Burberry zip-up and grey shorts, with a possible baby bump.
It's important to note that workout and outdoor apparel can sometimes create the illusion of a baby bump, even if there isn't one, and Suki has a slim figure.
Neither Suki nor Robert's representatives have confirmed her pregnancy.
Typically, women don't announce their pregnancies until after the first trimester, which is at least three months along.
Some expectant mothers can start showing as early as sixteen weeks into their pregnancy.
Suki is currently touring the United States with her band, and the couple keeps a low profile, not sharing their personal lives on social media.
