AceShowbiz - Brooke Mueller has found support in her twin sons after being embroiled in the investigation into Matthew Perry's death. The actress, who shares Bob and Max with ex-husband Charlie Sheen, was joined by the teenagers while celebrating her 47th birthday over the weekend.

When posing in front of a camera at the Saturday, 17 August event, Brooke and her sons flashed sweet smiles. Speaking about the special moment, she told the photography agency, "I'm very grateful for my kids."

The party was held at the Beverly Hills, California, home of Brooke's mom, Moira Fiore, and stepfather, Jon Fiore. Among those in attendance were boxing legend Sugar Ray Leonard and comedy duo Cheech and Chong.

Brooke's reunion with her kids arrived after she emerged as a key figure in the investigation of Matthew's death. While Brooke and Matthew were friends, meeting in rehab and reportedly forming an unexpected bond, the authorities have scrutinized her connection to his death.

According to InTouch Weekly, Brooke has been questioned multiple times and has cooperated fully with investigators. Police executed a search warrant at the sober living facility where Brooke resides, confiscating an iPhone and a laptop. Despite her cooperative stance, Brooke has hired legal representation and remains tight-lipped about her role in the tragic event.

Her complicated history with substance abuse and her efforts towards sobriety add another layer to the investigation. An insider disclosed in InTouch that the mom of two "is adamant she had nothing to do with Perry's death" and stresses her innocence while navigating the legal scrutiny.

While multiple individuals, including a doctor and several dealers, have been arrested, Brooke was reportedly not among the suspects. Matthew's death sparked a criminal investigation into the source of his ketamine. Authorities reportedly obtained text messages detailing discussions about the drug, delivery methods, and payment. The identities of those arrested have not been released.
