If words like “omigod” repeated in upbeat songs and gratuitous usage of the color pink turn your stomach, then you should probably stay away from Legally Blonde, a musical based on the 2001 film starring Reese Witherspoon. Just as she does in the film, Elle Woods challenges preconceived notions about blondes when she transforms herself from a bubbly Delta Nu president into a hard-working Harvard Law frosh. With her well-dressed Chihuahua (“Bruiser”) in tow, Woods lands a coveted internship, helps solve a murder case, graduates valedictorian, and, more importantly, realizes Warner — the guy who dumped her for someone more “serious” — wasn’t Mr. Right after all. $20.75-$70.75, 8pm Wed, Jan 19; 8pm Thu, Jan 20; 8pm Fri, Jan 21; 2pm & 8pm Sat, Jan 22; 2pm & 7:30pm Sun, Jan 23; the Majestic Theatre, 224 E Houston, (210) 226-3333, majesticempire.com.
