They're still ON! Jennifer Garner and off-again-on-again beau John Miller met up for breakfast at the Brentwood Country Mart's Farmshop -- a west-side hotspot -- on Wednesday morning and the two looked absolutely giddy!

John had his arms around Jen's waist -- clearly not afraid of showing a little PDA -- and Jen giggled and flirted before the pair said goodbye. Parting is such sweet sorrow! But John had a BIG smile on his face :)
