It might not be the best time for McDermott and Spelling to expand their family. The promo also shows them arguing and McDermott wondering aloud why Spelling is still with him after he was caught cheating last year. (At one point, curiosity gets the better of Spelling and she looks at a picture of the woman he was caught cheating with.)

McDermott and Spelling are already parents to four children: sons Liam, 7, and Finn, 2, and daughters Stella, 6, and Hattie, 2.
