Dax Shepard (AKA 陆 of what may be the cutest matching couple ever) and #dadgoals actor Ashton Kutcher are no strangers to the element of surprise, especially when it comes to their wives 鈥 check out this 2005 throwback of Ashton punking Mila, and who could forget the time Dax caused Kristen鈥檚 epic sloth meltdown?

The pair teamed up on Ellen yesterday to once again astonish their lady loves (appearing together to promote their new flick, Bad Moms), first with a sweet video message and then by unexpectedly joining them onstage (with flowers!) for what quickly turned into what may have been the best game of 鈥淣ever Have I Ever鈥 we鈥檝e ever seen.

Ellen got right down to business, asking the couples the hard questions, (鈥渉ave you ever hooked up on set?鈥), and some of their answers? Just may shock you! Read on below to see just what bombshells the couples revealed.

1. Neither couple has ever been to a nude beach. 鈥淪orry, guys 鈥 this Hollywood lifestyle鈥檚 not as exciting as it鈥檚 advertised,鈥 Dax said.

2. All four have swapped toothbrushes with their sig others. 鈥淚 don鈥檛 know that we HAVE separate toothbrushes,鈥 Dax quipped.

3. BOTH pairs of lovebirds have (gasp!) hooked up on set. Oh yes, dear readers. Oh yes!

4. Both couples have *probably* not 鈥渇allen asleep while making love.鈥 Kristen seemed ever-so-slightly confused about this one.


5. They 鈥済room鈥 (not wax!) each other鈥檚 body parts. 鈥淗e groomed me while I was pregnant,鈥 Mila explains of Ashton.

6. Mila is the only one of the bunch to have never thrown something of her S.O鈥檚 away that she hated without telling them. 鈥淓very time [Kristen] goes away for more than 48 hours, I get rid of about 20 things,鈥 Dax confessed.

7. They have all *probably* been in handcuffs. Again with some confusion on the part of Dax and Kristen, who weren鈥檛 entirely sure if Ellen meant of a law-abiding or more sexual nature.

8. They鈥檝e all given their partner a massage. No big shocker here 鈥 鈥淥f course, of course, who doesn鈥檛 like massages?鈥 Ellen said.

And there you have it! Eight fun facts we never knew we needed to know, but are so, so glad we do.
