Jennifer Lopez With Boyfriend Casper Smart at American Idol

Jennifer Lopez arrived for the third day of American Idol Hollywood Week auditions in Pasadena yesterday. She waved to fans and entered the arena solo, and later in the day she got a visit from her boyfriend, Casper Smart. Casper made a low-key entrance though a back door. It wasn't apparent, though, if he arrived in the Bentley Jennifer allegedly gave him as a gift!

J Lo and Casper's relationship seems to be going strong following their romantic Thanksgiving trip to Hawaii. One person, though, might not be thrilled. Her ex-husband Marc Anthony is reportedly unhappy about Casper and is very "stressed" over the situation. Jen's surprising split from Marc grabbed major headlines back in July, and it ranks among the most shocking celebrity breakups of 2011.
