Help with adding an apostrophe to the site tagline

[RescoCCC]

This is what I want to appear:

Welcome to Mama C's
Where magic, the New Age, and pop culture collide

Right now it appears without the apostrophe, and this is how I have it coded:

define('HEADER_SALES_TEXT', 'Welcome to Mama Cs<br /><i><font size="4">Where magic, the New Age, and pop culture collide</font></i>');

Now, I know I can add \' like this: Mama C\'s, and that works. The problem is that when I do it, the second line vanishes. Any ideas?
