The Dublin-born striker was photographed at the memorial party last month commemorating Alan Ryan, 32, who was shot dead in the city in September.
A bar owned by the Stokes family hosted the event, during which a band played 'The Ballad of Alan Ryan'.
On the day of Ryan's funeral, Stokes wrote "Thinking of you Alan..." on his Twitter account, which led to death threats.
I am not going to moralise to him, but you cannot damage the reputation of the club.
Lurgan man Lennon did not detail how the incident involving the Ireland international had been handled, but said disciplinary action had been taken.
He told the Herald: "We spoke to him. He is aware of that now. It has been dealt with internally."
Lennon said he believed Stokes had damaged Celtic's reputation but thought the 24-year-old player had learned from the incident.
Ryan, 32, was the head of the Real IRA in Dublin was gunned down in broad daylight, and a volley of shots was fired at his funeral. It is alleged his faction was behind extortion rackets in the city.
Stokes signed a four year deal with Celtic in August 2010, after spells with Sunderland, Arsenal and Falkirk. He earned his first international cap for the Republic of Ireland against San Marino in February 2007, but has been out on injury since July.
