AceShowbiz - Blake Shelton is being generous with his and Gwen Stefani's NSFW routine. On Thursday, December 20, the "God Gave Me You" singer stopped by "The Ellen DeGeneres Show" where he offered viewers some graphic details about her sexy bedtime routine with his singer girlfriend.

During the episode, "The Voice" coach joined Sandra Bullock for a round of "5 Second Rule". Host Ellen DeGeneres asked the "Ocean's 8" actress, "Sandra, name three things you watch on TV after the kids go to bed."

The 54-year-old Oscar winner then replied, "Porn, cartoons and cooking shows," before adding, "Please don't air this when my kids can see it!"

Ellen then asked Blake the same question and it appeared that their bedtime routine wasn't that different. "Oh, my God. Watch porn, cookin' shows and Instagram," he said. However, Blake shared that they didn't watch porn every day as he said, "We can't do that every time." Sandra agreed, though Ellen believed that "you can do whatever you want."

In addition, Blake also shared what Stefani makes fun of him for the most. "My hair, my socks and the same shirt I wear every day," he replied.

Blake and Gwen started dating in 2015 amid the No Doubt singer's messy divorce from musician Gavin Rossdale. The former couple shares sons Kingston, 12, Zuma, 10, and Apollo, 4. Blake, meanwhile, had just split from ex-wife Miranda Lambert when he started dating the "Hollaback Girl" hitmaker.

Gwen previously said on "Today" show that "there is zero pressure" in her romance with the country singer. "I think that everybody ... when there's trauma, the way that we had trauma back in the day, like, going through all these hard times to get to a place where you find somebody that's, like, your best friend that you know that you can depend on and trust and just get through life, I think that we're just trying to be in the moment as much as we can," she shared.
