Rob joined his pregnant fiancé for the launch of her Chymoji app at the Hard Rock Cafe in Hollywood which doubled as a birthday celebration.

The star, who has previously struggled with weight issues, appeared significantly slimmer and healthier and wore his signature baseball cap.

The pair only had water at their table inside the club (Blac is pregnant with Rob's child) and Blac reportedly made every single club goer download her emoji app in order to enter the party.
