Suki Waterhouse interrupted her performance to spill that shes pregnant in a sweet announcement on Sunday.

The actor and singer, who has been romantically tied to Robert Pattinson since 2018, broke the news to fans at Mexico Citys Corona Capital Festival as she explained her outfit choice.

I thought Id wear something sparkly today because I thought it might distract you from something else thats going on, said Waterhouse as she motioned toward her belly.

She added that shes not sure if its working as fans in the crowd cheered before breaking into her song Nostalgia .

HuffPost has reached out to representatives for Waterhouse and Pattinson.

Waterhouse is expecting her first child with The Batman star roughly five years after the pair reportedly began dating.

The two were seen together in July 2018 on a date night where they watched Mamma Mia! Here We Go Again in London, E! reported .

The pair reportedly lived together in London as Pattinson filmed The Batman in 2020, as well.

Pattinson told Jimmy Kimmel last year that he watched the movie with his girlfriend, who he said was not normally into watching superhero movies.
