Dear Commissioners:
On behalf of MML Equity Fund, MML Managed Bond Fund, MML Money Market Fund and
MML Blend Fund (the "Funds"), four of the series of MML Series Investment Fund
(the "Trust"), I am filing a certification pursuant to paragraph (j) of Rule 497
under the Securities Act of 1933, as amended. In this regard, I certify that the
form of prospectus and Statement of Additional Information that would have been
filed under paragraph (b) or (c) of Rule 497 would not have differed from that
