Kayleen McAdams is NOT the mother of "Sherlock Holmes" star Jude Law's fetus.

And she is not pregnant at all. And she has  never met Jude Law. Nor did Rachel make Jude 'fess up to fatherhood!

Actress/model Samantha Burke's attorneys have just released the following statement:

"Ms. Burke can confirm that she did in fact have a relationship with Mr. Law and that she has informed Mr. Law that she is expecting his child later this fall. Since informing Mr. Law of the pregnancy, he has been nothing but responsive and supportive of Ms. Burke and the pregnancy."

Could Jude Law's baby mama be Kayleen McAdams, the sister of Jude’s "Sherlock Holmes" costar Rachel McAdams, above?

Sienna_millllller She's an adorable 27-year-old Hollywood makeup artist  and some websites are identifying her as the  “secret mother.”

Some gossip sites have Jude and Kayleen hooking up last Christmas in New York when the actor was shooting on "Holmes"

Web buzz has her seven months pregnant and reports are that Rachel made Jude publicly admit his paternity or she would not do any press with him for "Sherlock."

We don't believe this for a minute. For one thing, her publicist says, "This is completely untrue. Kayleen hasn't even ever met Jude Law."

And we believe her.

However, she sure looks like Jude's type. Click here to see her.

Cute, perky, blond. In fact, she looks eerily like Sienna Miller, left, in her Edie Sedgwick "Factory Girl" days
