  We study the decays of $B_{s,d} \to l^+ l^- \gamma (l=e, \mu,\tau)$ within
the light-front model. We calculate the tensor type form factors and use these
form factors to evaluate the decay branching ratios. We find that, in the
standard model, the branching ratios of $B_{s(d)} \to \l^+ \l^- \gamma$ ($\l=e,
\mu,\tau$) are $7.1\times 10^{-9}$ ($1.5\times 10^{-10}$), $8.3\times 10^{-9}$
($1.8\times 10^{-10}$), $1.6\times 10^{-8}$ ($6.2\times 10^{-10}$),
respectively.
