At first, Lamar didn't seem to understand much of the game or how it worked, and he struggled to grasp concepts such as jury voting and even the host’s name. But his social skills and openness with his struggles ingratiated himself with the other houseguests. And it certainly helped that he got brought in early on working with the power couple of Miesha Tate and Todrick Hall, while also forming his own close relationship with Todd Bridges.
Lamar was very open with the other houseguests about his individual game. And it caused him to be candid in a game of double-talk. He openly told Miesha that he nearly voted for her when she was nominated, and became part of a coalition of himself, Todd, and Cynthia Bailey to demolish the duo. Unfortunately, he did not do well in any of the competitions, losing chances of power when he needed it most. Todrick won Head of Household and lavishly nominated him and Todd, intending to target the latter as the bigger threat. But when Todd won a crucial veto, Lamar became the new target. He was then evicted in a 2-1 vote, with Todrick casting the tiebreaker vote.
On Finale Night, Lamar was nominated for America’s Favorite Houseguest along Carson and Shanna Moakler, but lost to Carson.
