Robert Pattinson may have famously said that his glittering countenance was “the skin of a killer” in the Twilight movies where he rose to fame as vampire Edward Cullen, but girlfriend Suki Waterhouse is making headlines for some shimmer of her own.

“I thought I'd wear something sparkly today to distract you from something else I've got going on,” Waterhouse, 31, said from the stage at the Corona Capital Festival in Mexico City Sunday. That something else? What appeared to be a baby bump, swathed in a figure-hugging pink sequined minidress. “I’m not sure if it’s working.”

The moment of Waterhouse's big reveal was captured by audience members and shared to social media.

Waterhouse has been romantically linked to Pattinson, 37, since 2018. In his post-Twilight career, Pattinson has moved on to several other film roles, including the lead in The Batman. Waterhouse, for her part, is a model and musician, and was part of the ensemble of this year’s Daisy Jones & the Six streaming TV adaptation alongside Riley Keough.

Representatives for Robert Pattinson and Suki Waterhouse did not respond to requests for comment.
