We calculate the masses and decay constants of the P-wave strange-bottomed mesons Bs0 and Bs1 with the QCD sum rules, and observe that the central values of the masses Bs0 and Bs1 are smaller than the corresponding BK and B* K thresholds respectively, the strong decays Bs0 → BK and Bs1 → B* K are kinematically forbidden.They can decay through the isospin violation processes Bs0 → Bsη→, Bsπ0 and Bs1 → Bsη→, Bs*π0. The bottomed mesons Bs0 and Bs1, just like their charmed cousins Ds0(2317) and Ds1(2460), may be very narrow.
