The latest results of CMS in the area of exotic quarkonium decays will be presented: observation of a peaking structure in $J/psiPhi$ mass spectrum in the decay $B^pm rightarrow J/psi Phi K^pm$, search for new bottomonium states in $Upsilon(1mathrm{S})pi^+pi^-$ mass spectrum, measurement of prompt $J/psi$ pair production.
