On Tuesday's episode of The Young and the Restless, Chelsea's lie about baby Connor comes out.

At home, Chelsea says Adam came because he was concerned after overhearing Dylan tell Billy about Connor's eye problem, revealing that Adam used to have the same disease.

Dylan says the odds of her ex having the same eye disease as their son is probably a million to one.

Finally, Chelsea admits that she told Adam that Connor is their son. Dylan says, "You'd never let me name him after my father if he wasn't mine. Would you?"

Chelsea again admits he's Adam's son. Dylan yells that everything's changed now that Connor's not his son and their entire relationship has been built on a huge lie. He leaves, even though Chelsea begs him to stay.

Meanwhile, Adam arrives at Avery's apartment and tells her he wants her to sue Chelsea for custody of his son. Adam wants her to represent him. Avery secretly hopes to protect Dylan and tells Adam to wait a few days until he has cooled down.

Later, at the tackhouse Avery tells Nick about Adam's visit. Nick groans, "What a mess."

Avery's upset that Chelsea used Dylan, admitting she is "overwhelmed."

Although wedding plans are going as planned, Avery wonders if she's ready to marry -- and insists she's not looking for an excuse to postpone.

Stay tuned for more spoilers tomorrow.
