Teddi Mellencamp Arroyave just announced that she's pregnant with her third child, which was a complete surprise for The Real Housewives of Beverly Hills cast member and her husband, Edwin Arroyave. Teddi previously went through IVF to conceive her two children, daughter Slate, 6, and son Cruz, 5 (Edwin has a 10-year-old daughter Isabella from a previous relationship). She shared that her kids are "so excited about the baby" — and the RHOBH ladies are just as thrilled. In fact, they're starting to plan for Teddi's son or daughter's arrival already.

Erika Girardi told Us Weekly, "I am so excited to welcome the first baby of Beverly Hills. I’m loving watching Teddi’s journey and can’t wait to squeeze this little bundle of joy! I’m not sure if her baby shower can compete with Andy [Cohen’s] baby shower…. but we are certainly going to try!”
