  We present the results on two-particle Bose-Einstein correlations measured in
proton-proton collisions at center of mass energies of sqrt{s}=0.9 TeV,
sqrt{s}=2.76 TeV and sqrt{s}=7 TeV registered by the ALICE experiment at the
Large Hadron Collider. Detailed analysis reveals that the three dimensional
experimental correlation functions do not have Gaussian shape in two
dimensions. We found that they are better described by an exponential
functional form in the outward and longitudinal directions, while the sideward
remains a Gaussian. This is interpreted as a result of a significant
contribution of strongly decaying resonances to the shape of the emission
region.
