Lance Armstrong -- My Baby Mama's Ripped ... And Looks Damn Good in a Bikini

The Lance Armstrong image makeover continues ... now with more bikini photos!!!

The disgraced cyclist was out in Miami Beach this week with his longtime GF Anna Hansen -- who also happens to the mother of 2 of his 5 children.

Anna looks damn good ... and in the pics, she's all over Lance -- suggesting that if a hot chick with a hardbody can forgive the guy, maybe we can all move on too.

Then again ... he did cost us 7 frickin' titles!!!
