Rosa Acosta is thrilled for her ex, Rob Kardashian and Blac Chyna’s future together.

While at Rosa’s pop up shop, Cossamia in Los Angeles, the Love & Hip Hop Hollywood star shared with HipHollywood her thoughts on Rob and Blac’s recent engagement and baby announcement. “So happy for them. I actually was at their event and saw them, they are really happy. I’m happy for them.”

She added, “I’m happy to see everybody doing good. I like when people are happy.”

Rosa and Kardashian quickly dated back in 2011, but in that brief period, Acosta had a moment where she thought she was going to be giving birth to Rob’s first child.  As chronicled on E!s Khloe and Lamar, Rosa took a pregnancy test and it was apparently positive.

It was later revealed that Rosa sadly miscarried.

Rob and Blac are set to wed and are expected to give birth to their first child together later this year.
