Tristan Thompson's lawyer demands Sydney Chase show the racy text messages she claims she received from Khloe Kardashian's beau 'or risk facing lawsuit'
Tristan's lawyer Marty Singer has reportedly fired off a second letter to Chase after she refused to comply with a cease-and-desist earlier this week
Singer is requesting that Chase show proof of her claims, including the salacious messages she says she has from Khloe Kardashian's boyfriend
In the new legal warning, Singer accuses Chase of 'changing the purported 'facts' to fit [her] story' and says she's just after fame
Chase has claimed that she 'hooked up' with the NBA player in January
