We spotted Brittny Gastineau arriving at BOA steakhouse in a revealing dress last night.

Brittny has spoken out to deny rumors she is dating Olympic swimmer Michael Phelps. She also denied she is pregnant after she was allegedly spotted buying a home pregnancy test.

She explained to People magazine, "I’m too busy to date anyone because I’m working so hard on my jewelry line." The 28-year-old reality star is the daughter of former NFL star Mark Gastineau.
