Overexposed! Lisa Rinna and Kathy Griffin Flash Too Much Skin Over Weekend (PHOTOS)

Guess Who? Cleavage!
Which hot Hollywood lady is this?
Lisa Rinna and Kathy Griffin may be over 40, but that’s not stopping them from flashing as much skin (if not more) as starlets half their age.

The former Melrose Place star, 48, attended Simon G Jewelry’s ‘Summer Soiree’ on Saturday, but it seemed her LBD was showing off more than just her curves as cameras exposed a braless Lisa.

Meanwhile, 51-year-old Life on the D-List star, Kathy, flashed her underpants on purpose during an event with Gloria Estefan at Seminole Hard Rock Hotel & Casino in Hollywood, Florida on Saturday.

But they’re not the only celebs to show a little too much skin.

From Lady Gaga to Kelly Bensimon, click the pics to see the celebs who’ve shown a little too much.
