Kutcher, 40, steamed up the sheets with blond bombshell Cuthbert, 35, in the Netflix series' first season, and he wanted her back on the show, sources said.
The only problem? Kunis nixed the idea!
"Ashton loved working with Elisha, and thought their scenes should be even sexier," an insider told Radar.
"But Mila's not having it, even though Elisha is happily married and not at all attracted to Ashton."
What's more, Cuthbert didn't even want the job.
"Elisha wants to reduce her workload, not increase it," said the insider.
Netflix has made no official announcement yet if Cuthbert will be returning to the show for Season 2.
Cuthbert isn't the only one 34-year-old Kunis is "jealous" about — she also sees Ashton's ex-wife, 55-year-old Demi Moore, as a rival!
"Ashton has always praised Demi for how good she looks , and that bothers Mila," said a source.
