Bobbi Kristina Brown’s father, Bobby Brown, was spotted attending a comedy show Tuesday night, a week after his daughter's burial. According to reports, Bobby Brown has been finding it hard to cope with the loss of his daughter.

The only daughter of Bobby Brown and the late Whitney Houston died at the age of 22 on July 26 after remaining in an unresponsive state in several medical facilities since Jan. 31. On Tuesday, Bobby Brown was seen talking to his fans outside the Ha Ha Cafe Comedy Club in Los Angeles. Before this, the R&B singer was last seen wiping his tears after Bobbi Kristina’s funeral at St. James United Methodist Church in Alpharetta, Georgia.

"He was in a good mood," a source told People magazine. "He was jovial," a second eyewitness reportedly said, adding: "He was fairly open with his feelings with fans, stating that he was heartbroken."

Earlier this month, a friend of Bobby Brown told the U.K.’s Daily Mail that the 46-year-old feels that Bobbi Kristina’s death is his fault as he failed to force her into rehab.

“He told me he should have insisted Krissy get help for her drug addiction and he should have forced Nick Gordon to move out of her townhouse and leave her alone -- legally, if necessary,” the friend told the Daily Mail.

Bobbi Kristina was buried next to her mother on Aug. 3 at Fairview Cemetery in Westfield, New Jersey. Her boyfriend, Nick Gordon, is being investigated after a lawsuit was filed against him, alleging that he abused his girlfriend and stole her money.

New details about Bobbi Kristina and Gordon's troubled relationship emerged last week after her court-appointed conservator Bedelia Hargrove filed an amended lawsuit Friday that alleged Gordon gave her a "toxic cocktail" and then put her facedown in a bathtub. Gordon, who was not allowed to see Bobbi Kristina during her hospitalization and was barred from attending her funeral service, revealed last week that he will host a private ceremony to remember and honor his girlfriend.
