GLENDALE, Ariz. (AP) — Rihanna was pregnant with her second child as she performed her Super Bowl halftime show Sunday.

The singer’s representative confirmed the pregnancy shortly after she ended her 13-minute set at Super Bowl 57.

The baby bump that was visible in the tight clothes she wore under her baggy red jumpsuit during the show set off a wave of social media speculation that she might be pregnant again.

The 34-year-old has a 9-month-old son with rapper A$AP Rocky.
