Kate Upton's family is NOT embarrassed by her jiggly supermodel ways ... this according to her uncle, who also happens to be a friggin' U.S. Congressman!
TMZ spoke with Fred Upton (R-Mich) in D.C. yesterday ... who ensured us Kate is nothing short of a "great gal" ... which we already knew because of this ... and this ... and this ... and this.
But the Upton family is more than hotness and politics ... they're also SUPER LOADED ... because Kate's great-grandfather started the WHIRLPOOL corporation back in 1911!!!
Fun Fact -- Whirlpool was the first company to offer employees paid vacations. So next time you take some time off, you should probably thank the Upton family ... by watching this.
