Same surname, different model. :-)
I originally featured Maureen Gallagher in March 2011, but these are the first color pictures of her that I've included here.
Both are from fashion shows. As you can tell, Maureen Gallagher looks very regal in a conservative outfit with a hat, like the one in the above photo, but she looks spectacularly stunning in anything strapless, as seen below.
Who are the designers? Yeah, like I really care about that! ;-)
