People magazine is a very well known and reliable source of information. An article by Natasha Dye and Julie Jordan says that Rihanna is in fact pregnant with her second child. Natasha is a verified “Sports writer-reporter for People Digital. She's also written for The New York Post and spent four years as West Coast Editor at Popstar”, according to people.com. Julie Jordan is an editor for People magazine. Similarly to Natasha Dye, Julie is also a very reliable source for many reasons. She also worked with “the brand for 25 years”(People). This makes them credible writers.
In another People article, “Pregnant Rihanna Cradles Her Baby Bump in Sweet Photo Taken During Super Bowl 2023”, it includes a photo of Rihanna cradling her baby bump on and off stage at the Super Bowl 2023. This pose is one most pregnant women use and most non-pregnant women do not use.
From the last article I read called Rihanna Is Pregnant, Expecting Her 2nd Child With ASAP Rocky by Caitlyn Somers and Yana Grebenyuk they confirmed that Rihanna's baby is A$AP Rockys. The article states she is “expecting her second baby with ASAP Rocky after hinting at the pregnancy during her performance at Super Bowl LVII on Sunday February 12, 2023”(USmagazine).
Overall these pictures and three articles are clear proof that Rihanna is pregnant with her second child with A$AP.
