Rowland announced that she and Weatherspoon are expecting their second child together on the November cover of Women's Health. "We had been talking about it loosely, and then COVID happened, and we were just like, 'Let's see what happens,' " Rowland told the magazine, before admitting that she got pregnant right away.

The "Coffee" singer said that she hesitated to share the news publicly — especially during a time when the country was facing the coronavirus pandemic.

"But you still want to remind people that life is important," she said at the time. "And being able to have a child ... I'm knocking at 40's door in February. Taking care of myself means a lot to me."

Above anything else, however, Rowland said her son can't wait to welcome the new addition into their family. "Titan already named the baby," she told PEOPLE last month. "He knows what he's having and he is excited."

"But when the baby's here, that's when you're really gonna know what the deal is, because he's used to all the attention," Rowland added.

As for a third child, Rowland revealed that she's "closed for shop, ladies and gentlemen." She added, "I didn't know it was going to be like this the second time around, which makes it my last, that's for damn sure."
