Shanna Moakler says she's not trying to get with Lamar Odom ... despite flirting with him on "Celebrity Big Brother" and upsetting her boyfriend in the process.
Shanna, who was recently evicted from the 'CBB' house, tells TMZ ... she's not interested in Lamar, romantically or in any capacity -- but she understands why her boyfriend, Matthew Rondeau, is pissed about her antics in the 'CBB' house.
TMZ broke the story ... Shanna's boyfriend, Matthew Rondeau, was not happy with the subtle sexual innuendos flying back and forth between SM and LO, and was having second thoughts about popping the question.
