We consider double spin asymmetries for longitudinally polarized leptons and transversely polarized protons in diffractive vector meson and production at high energies within the two-gluon model. The connection of the two-gluon approach with skewed gluon distributions is discussed. The asymmetry predicted for meson production is quite small. The AlT asymmetry for production contains two independent terms which are large and can be used to obtain information on the polarized skewed gluon distributions in the proton.
