We perform optical photometric and polarimetric monitoring of a sample of gamma-bright blazars using 0.7-m AZT-8 (Crimean Astrophysical Observatory) and 0.4-m LX-200 (St.Petersburg) telescopes, as a part of WEBT/GASP project. We report that PKS 1510-089 reached R=14.22 in the night of 2019 April 28, TJD 58602.5. This is 1.5 mag brighter than the quiescence level of this season; intranight brightening continues this trend. The degree of polarization increased from moderate 1- 3% in previous nights to 15-17% during last night. R band light curve for PKS 1510-089 can be seen on our web-page.
