We present state-of-the-art predictions for off-shell $t\bar{t}b\bar{b}$production with di-lepton decays at the LHC with $\sqrt{s}=13$ TeV. Results areaccurate at NLO in QCD and include all resonant and non-resonant diagrams,interferences and finite-width effects for top quarks and $W$ bosons. Wediscuss the impact of QCD corrections and assess theoretical uncertainties fromscale and PDF dependence at the integrated and differential level. Additionallywe investigate the size of contributions induced by initial-state $b$ quarks tothe NLO cross section.
