The 44-year-old reality star and 50-year-old television personality discussed the possibility of baby No. 6 during son Beau's red carpet debut at the Big City Moms Biggest Family Shower Ever event Sunday in Los Angeles.
"Everything is so good," Spelling told E! News. "It's been a blessing having baby Beau. I think not just for our family but for us. Our love has grown stronger. My husband definitely has a lot of patience."
"Never say never," McDermott said of having more kids. "Our hands are pretty full right now, so we'd like to just enjoy the little ones we have right now. It's absolute insanity ... It's a happy, crazy, loving chaos."
Spelling and McDermott share 10-year-old Liam, 9-year-old Stella, 5-year-old Hattie, 4-year-old Finn and 6-month-old Beau, while McDermott is also dad to 18-year-old Jack. Spelling previously discussed the possibility of another child following Beau's birth in March.
"I forgot how much I loved being pregnant," she shared. "I love the connection. You are never alone."
Spelling is known for playing Donna Martin on Beverly Hills, 90210, and has since starred on the reality show True Tori. McDermott portrayed Renfield Turnbull on Due South, and now hosts Chopped Canada.
