Pamela Anderson and Brandon Lee Are Showing a 'United Front' Against Tommy Lee (Exclusive)

By

Pamela Anderson is doing everything to be supportive of her 21-year-old son, Brandon Lee, after Brandon’s highly publicized altercation with his father, Tommy Lee, earlier this month, a source tells ET.

On Monday, 50-year-old Pamela and Brandon were spotted out to dinner together at celeb hot spot Craig’s in West Hollywood. According to our source, they went out to dinner in public to show a united front against Tommy.

“Tommy is seething," the source claims. "He is watching every move Brandon makes. He wants his son to beg for forgiveness, but that won’t happen. He wants Brandon to show remorse and doesn’t feel he has done anything to have deserved this."

Earlier this month, Tommy shared a picture of his bloodied face on Instagram, claiming that Brandon assaulted him. Brandon later claimed the altercation stemmed from his father's alleged alcoholism, which the 55-year-old Motley Crue drummer denied. The incident led to a criminal investigation by the Los Angeles County’s Sheriff's Department.

“Brandon is sticking to his story that this was self-defense and that his father needs rehab," our source says. "Pam has made sure that they are ready with a team just in case Tommy doesn’t drop the charges. No one thought Tommy would take this so far. His family and friends have been pushing him to drop the charges, but he is being stubborn."

“Everyone hoped he [Tommy] was doing this to scare Brandon, but at this point they are worried if Tommy waits to drop the charges there is a good chance the DA could charge him anyway," the source adds.

The source notes that the drama has "been hard on everyone."

“Right now things look grim for the whole family," the source says. "This has put a huge wedge between father and son. The last thing Brandon needs is to have a record because of his father. It could ruin their relationship for good."

ET has reached out to Tommy's rep for comment.

Pamela and Tommy were married for three years before divorcing in 1998, and share two sons together -- Brandon and his younger brother, 20-year-old Dylan. Following Brandon and Tommy's altercation, Pamela spoke out in defense of her eldest child.

"I have complete faith in Brandon and his team to resolve this unfortunate and sad situation regarding his father," the former Baywatch star posted in a statement to her website titled "Alcoholism Is the Devil." "I pray Tommy gets the help he needs. His actions are desperate and humiliating -- he is a disaster spinning out of control and he is not acting like a father."

"I feared things might escalate," she continued. "But -- knew this might be what it took to heal old wounds. Him blaming his son or us for anything is delusional.  ...  I stand beside my son who acted out of self defense and was scared for his life. Nobody understands the lifetime of disappointment this man has brought our family. Consistently the centre of sadness, drama and confusion. Jealous of his sons talent and beauty from the day they were born."

Tommy responded with his own statement, saying, "Truthfully this whole situation has become so depressing and out of control. My heart was broken when my son punched me. Should I have posted it on social media? Probably not."

"My alleged 'alcoholism' has nothing to do with this," he added. "I've been in therapy and working on myself, my fiancée is the one who got me into therapy! The boys never once came and talked to me and told me they felt I had a problem. However, my fiancée has been helping me since we've been together."
