Ashlee Simpson and beau Evan Ross attended the Beyonce concert at the Staples Center in Los Angeles on Tuesday night, and the duo held hands on the way out. Ash and Evan made their first appearance back in July, so it looks like they are right around the 6 month mark with their relationship.

While it hasn't been that long, Evan basically revealed in a recent interview that Jessica's little sister is marriage material! "It's amazing. I'm so in love," he gushed to OMG! Insider last month. "We [have] amazing things going on and we inspire each otherShe [is] the one." Wow! And not only that, but when asked if he plans to marry his lady love, Evan exclaimed, "For sure!"

Think the two will get engaged over the holidays?
