Now that TRL is ending its 10-year run on MTV, Christina Aguilera is taking to the Web to premiere her new music video for her hit single, "Keeps Gettin' Better," on Monday afternoon.

The singer, 27, chose iLike.com, a social music Web site and Facebook application, to release her new video. In it, Aguilera travels through time – and costumes – to the present day.

"I really enjoyed making the video," Aguilera says. "Being an artist who likes to play around with different looks, it was a lot of fun to portray various characters within the same shoot."

The song will be featured on her greatest hits CD, which includes 10 of her best singles and another brand new song, "Dynamite." It will be available exclusively at Target stores on Nov. 11.
