The 29-year-old reality TV star was spotted chatting to the newly-single 'Blurred Lines' hitmaker, who split from wife Paula Patton earlier this year, as she enjoyed a girls' night out in Los Angeles on Wednesday (06.08.14).
A source told UsMagazine.com that the former Playboy model, who has son, Hank IV, four, and daughter, Alijah, 11 weeks, with her husband, seemed ''super casual, in really good spirits'' and was not wearing her wedding ring.
The insider added: ''It was fun, not crazy. Kendra was drinking, but she wasn't drunk.''
Robin briefly chatted to the blonde beauty at her table, but the source insisted: ''They don't really know each other.''
Kendra was also seen hanging out with her rapper pal Too Short following allegations Hank, 31, cheated on her with a transgender model while she was eight months pregnant with their daughter.
The eyewitness said: ''Too Short was really sweet, consoling her, trying to make her feel better. He gave her a big hug.''
It was previously reported that the model has consulted a divorce lawyer because she isn't sure she and Hank can repair their relationship.
Another source said: ''She's definitely serious about filing, but is also reviewing her options before she makes a final decision.''

The film is expected to continue without Mendes' involvement.
