‘TORI and Dean” is starting to score big numbers.

The Oxygen reality show, starring Tori Spelling and husband Dean McDermott, snared over 1 million viewers Tuesday night at 10 – the biggest audience in series history.

Viewership has been growing week to week since the show kicked off its third season last month.

Tuesday’s show also held a 22 percent viewership advantage over the season premiere of Lifetime’s “How To Look Good Naked,” hosted by Carson Kressley.

“Tori & Dean” wraps its season Aug. 5.
