Answer :

In the name of Allah, Most Gracious, Most Merciful
Assalaamu `alaykum waRahmatullahi Wabarakatoh
Your question is not clear. It does not specify who committed the adultery, the husband or the wife. From the subsequent statement, it appears that the wife committed the adultery, which is a major sin. In principle, she is a wife and her child would be regarded as born in wedlock. The husband will be regarded as the father of the child. Adultery does not constitute as automatic divorce.
And Allah knows best
