There were reports that Toni Storm is going to be included in WWE’s United Kingdom Championship tour in June which is true. Dave Meltzer reported on Wrestling Observer Radio that she told Stardom she needed to be back by the time the WWE tour started.
But it doesn’t look like she’ll be coming to WWE so fast because Casey Michael of Squared Circle Sirens reports she has a contract with Stardom through July. Although it is likely to happen eventually, she can’t sign anything with WWE just yet.
Toni Storm still has a STARDOM contract through July I'm told so I doubt she's signed with WWE as of right now but I'm sure it's coming.
