Despite writing a letter begging the Houston and Brown families to allow him to be in attendance, Nick Gordon was not present at Bobbi Kristina Brown's intimate memorial service on Saturday.

A source close to the Houston family tells ET that Gordon texted a family member on Saturday morning asking once again for permission to attend the funeral. His request was denied. 

Members of both families were in attendance, including Bobby Brown, Bobbi Kristina’s father; Pat Houston, Whitney Houston’s sister-in-law; and Leolah Brown, Bobby’s sister and Bobbi Kristina’s aunt, who was removed from the service after an outburst. Filmmaker Tyler Perry and singers Monica and CeCe Winans also participated in the service.

Gordon, who was Bobbi Kristina’s boyfriend until her death, penned a letter earlier this week asking Pat Houston and Bobby Brown to allow him to attend the funeral at St. James United Methodist Church.

ET obtained a copy of the letter, in which Gordon asks both families to “put your differences aside.”

"I'm asking you both for your blessing in regards to me attending Krissi's funeral," he wrote in the letter. "I do not want to cause any trouble or commotion so I'm emailing you privately in advance."

"I loved Krissi with all my heart and I am destroyed that she is gone and I need to say goodbye," continued Gordon, asking the family to “give me this chance.”

"Krissi loved me very much and she would want me there. Please consider this?" he wrote.

Although the two were not legally married, ET obtained footage showing Gordon still wearing his wedding band on his finger, along with Bobbi Kristina's ring around his neck.

While facing a civil lawsuit from Bobbi Kristina's conservator, Gordon has hired a high-powered legal team, including Jose Baez -- lead defense attorney for Casey Anthony, who was found not guilty of first degree murder of her 2-year-old daughter, Caylee Anthony, in 2011.

ET will have coverage throughout the weekend.
