Electromagnetic probes are excellent messengers from the hot and dense medium created in ultrarelativistic heavy-ion collisions. Since leptons do not interact strongly, their spectra reflect the entire space-time evolution of a collision. To quantify modifications in heavy-ion collisions, measurements in pp collisions serve as a reference. We present dielectron measurements with the ALICE central barrel detectors. The invariant mass distributions in the range 0<mee<3.3 GeV/c2 are compared to the expected hadronic sources for pp collisions at sqrt(s)=7 TeV. The cross section of virtual direct photons measured in pp collisions is compared to predictions from NLO calculations as a function of the transverse momentum.
