Lamar Odom insists he is ''alive'' and healthy.

The basketball player has had a turbulent few months with his four-year marriage to Khloe Kardashian rocked by claims of infidelity, while it has also been alleged he has a problem with crack-cocaine.

However, Lamar was spotted having lunch with a friend in Los Angeles this week looking well and insisted he's determine to be a ''nice guy''.

Speaking to a TMZ video paparazzo, he said: ''I'm alive. To some people basketball is life, to some people family is life. It's all about seeing people good and being a nice guy.''

The 33-year-old athlete says hasn't yet had the chance to wish Kim Kardashian 'happy birthday', after she celebrated her 33rd birthday and got engaged to Kanye West on Monday (21.10.13).

Lamar was quizzed on whether he had spoke to Khloe recently, to which he replied ''do you see my wedding ring on?''

Lamar's sporting career has taken a back seat of late because of his various personal problems but he is seemingly in talks with his old team the Los Angeles Lakers.

Although he is currently a free agent, Lamar revealed he ''could be a Laker'' but remained tight-lipped about his next move.
