‘THE Littlest Groom” had trouble finding big premiere ratings Monday night.

Fox’s two-part reality show finished third from 8 to 9 p.m. with 7.5 million viewers – far behind NBC’s “Fear Factor” and CBS’ combo of “Yes, Dear” and “Still Standing.”

On the show, which wraps next Monday night, a little person named Glen will choose between dating a woman his own size or someone of “average” height.

The mediocre showing of “The Littlest Groom” didn’t affect the penultimate episode of “My Big Fat Obnoxious Fiancé,” which notched 16 million viewers from 9 to 10 p.m.
