Guess who popped back up in the latest episode of How I Met Your Mother? Our girl, Lucy Hale (Aria)! The Pretty Little Liars star took a break from the plots and intrigue of the “A” game to appear on a show concerned with identifying the deal with a different mysterious figure: the mother.

For those unaware, Lucy plays Robin’s little sister Katie on HIMYM, appearing in one other episode prior to this way back in Season 2 of the show. But it was very cool to see Luce on the show again, especially as it made perfect sense given that the episode in question — Season 9, Episode 19 (“Vesuvius”) — dealt with Robin’s wedding day. Or more specifically, the story of how Robin broke a lamp on her wedding day. Of course, as part of her pre-wedding festivities, Robin got in a quick game of hockey with her little sister. Totally worth it to see Lucy in a hockey jersey!

Luce has been quite the cameo-maker as of late. In addition to the HIMYM appearance, she recently guest starred in an episode of Baby Daddy. The cameo actually came about when Baby Daddy actor Taj Mowry was interviewing Lucy for a behind-the-scenes feature for his show. Of course, it doesn’t hurt that Lucy is BFFs with star Jean-Luc Bilodeau.

Have you caught Lucy’s cameos? Which show do you want her to guest-star on next? Sound off in the comments below!
