It isn't explicitly stated in the show, but because we learn after episode six that all three boys have dark brown hair — and despite Rhaenyra and Laenor's matching blond color — it has been strongly implied that they are actually the children of Ser Harwin Strong, the Lord Commander of the City Watch.
Though Rhaenyra is married to Laenor Velaryon, all three of the young princes have brown hair, instead of the signature platinum locks that the Targaryens and Velaryons are known for.
Rhaenyra's three eldest sons all died fighting during the Dance of the Dragons, but her two youngest sons, the sons by her second husband, Prince Daemon, survived the civil war.

Daemon and Rhaenyra share two children together: Aegon III and Viserys II.
The episode doesn't really beat around the bush when revealing that Harwin Strong (Ryan Corr) is the father of Rhaenyra's children. He's there soon after baby Joffrey is born so he can meet him, and later on in the episode Jacaerys (Leo Hart) even asks his mom if Harwin is his real dad.
When finally did give birth to the baby, it is said that the child had a hole where her heart should have been, a tail, and scales for skin—a monster, as her mother had cursed her to be.
Rhaenyra has had a tough couple weeks. First, she finds out that her half-brother Aegon II has usurped the throne and that she will have to fight for her claim as queen. Then, she gives birth to a stillborn child. And finally she loses her second eldest son Lucerys to a dragon battle.
According to the accounts of Septon Eustace, prior to her turning sixteen, Rhaenyra lost her virginity to her uncle, Prince Daemon, after he seduced her.

He doesn't only ignore Laena on the issue, though, he actively ignores his daughter Rhaena (Eva Ossei-Gerning) as well, perhaps because she doesn't own a dragon like her sister Baela (Shani Smethhurst) or her parents.
Rhaenyra's sons are bastards. They're the illegitimate children of Rhaenyra and Ser Harwin Strong (Ryan Corr). The issue of the children's legitimacy is an open secret at court, with people turning a blind eye because the king does.
