The fan favorites of "Teen Mom" are expecting their second child together — and this time they're keeping their baby, according to a new US Weekly interview with April Stotts, Catelynn Lowell's mom.

The journey Catelynn and Tyler Baltierra, both 22, went through when they put their first child, daughter Carly, up for adoption in May 2009 was documented on the MTV show "16 and Pregnant." The couple were later featured on the network's show "Teen Mom." 

Stotts says her daughter is thrilled with the pregnancy news. "She was crying when she knew for sure and so I was like, 'Are you happy? Are you upset?' And she was like I’m happy!,'" her mom told Us.

The grandmother-to-be also revealed that Lowell is hoping for a girl, so she can buy "all the zebra stripes and pink stuff."

Lowell and Baltierra first announced that they were trying to get pregnant in April.

“I am an adult and I can tell when I’m ready and idc what ANYONE says I’m gonna do me!," Lowell wrote on Twitter. "We ARE READY for a baby."
