We report on charm production at LHC. The production of single c̄c pairs is calculated in the kt-factorization approachwith different unintegrated gluon distributions. Examples of transverse momentum distributions for charmed mesons are presented and compared to recent experimental results from LHC. Some missing strength is observed for most of UGDFs. Furthermore we discuss production of two c̄c pairs within double-parton scattering (DPS) and single-parton scattering (SPS) mechanisms. Surprisingly large cross sections, comparable to single c̄c pair production are predicted. We discuss first experimental results from LHCb collaboration on production of pairs of D mesons of the same flavour.
