  We report on charm production at LHC. The production of single $c \bar c$
pairs is calculated in the $k_t$-factorization approach with 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 $c \bar c$ pairs within double-parton scattering
(DPS) and single-parton scattering (SPS) mechanisms. Surprisingly large cross
sections, comparable to single $c \bar c$ pair production are predicted. We
discuss first experimental results from LHCb collaboration on production of
pairs of $D$ mesons of the same flavour.
