Who knew Kendra Wilkinson had a Mother complex?
Wilkinson is filming her cameo today, E! News has learned. No word what part the blond beauty plays in the storyline, which is being kept tightly under wraps.
Kardashian, meanwhile, shot her scene in front of a green screen and no other HIMYM actors were involved.
Wilkinson, 23, made headlines last month when she announced her split from Playboy founder Hugh Hefner and engagement to Philadelphia Eagles receiver Hank Baskett.
The How I Met Your Mother special is scheduled to air in January.
