Vanessa Bryant had some emotional support Monday in her trial against L.A. County over crash-site photos ... walking in shoulder to shoulder with Ciara and Monica.
The 2 singers arrived with VB and her daughter Natalia ... all the women forming a united front. They sat behind Vanessa during testimony from an internal officers with the Sheriff's Dept.
They never left her side ... at certain points in Monday's proceedings, Vanessa had to step outside -- and both Monica and Ciara went out with her.
