Vixen Amber Rose is good with numbers. The pregnant model went to social media to treat the world to a new equation-based selfie.

On Monday, Muva Rose low-key made her pitch for an early Woman Crush Wednesday crown.

This past weekend, Rose went to Instagram to single out her so-called pals for going ghost on her amid announcing a pregnancy and recently getting sick.

Earlier this month, Muva went to IG with a sneak peek at her tummy and reveal she’s soaking in good feelings in paradise.

A few days ago, reports emerged about Amber experiencing some early pregnancy pains and needing medical attention.

Sources close to Amber tell TMZ … she’s 13 weeks pregnant and is suffering from hyperemesis gravidarum … a severe type of nausea and vomiting during pregnancy. We’re told Amber was hospitalized at Cedars-Sinai Medical Center for a few days, getting IV treatments because she was sick and losing weight. The baby boy is due in October, close to Amber’s birthday … and we’re told she’s excited to share the same sign — Libra. (TMZ)
