The 31-year-old mother of two - who shares 1-year-old twins Zion and Jillian with Nick Cannon
De La Rosa who is not the mother this time around shared a funny sketch of content creator and comedian Brian Moller made highlighting.
In the skit, he jokes that Cannon "made an entire generation with one hand," trampling on the Kardashian clan.
Cannon broke the news with a video montage posted to Instagram that showed her and Bell participating in a maternity photoshoot.
Back in June, De La Rosa revealed she was pregnant with her third baby, but did not reveal whether or not Cannon was the father.
