Ladies and Gentlemen:

Pursuant to Rule
461 under the Securities Act of 1933, as amended, The Blackstone Group L.P.
(the “Partnership”) hereby requests that the effective date of the
above-referenced Registration Statement be accelerated so that it may become
effective at 1:00 p.m., Washington, D.C. time, on June 21, 2007, or as soon as
possible thereafter.  In this regard, the
Partnership is aware of its obligations under the Securities Act.

The Partnership acknowledges that:

·                  should the
Securities and Exchange Commission (the “Commission”) or the staff, acting
pursuant to delegated authority, declare the filing effective, it does not
foreclose the Commission from taking any action with respect to the filing;

·                  the action of
the Commission or the staff, acting pursuant to delegated authority, in
declaring the filing effective, does not relieve the Partnership from its full
responsibility for the adequacy and accuracy of the disclosure in the filing;
and

·                  the Partnership
may not assert staff comments and the declaration of effectiveness as a defense
in any proceeding initiated by the Commission or any person under the federal
securities laws of the United States.
