Celebrity Week In Review: Miley & Liam Call It Quits, Christina's Weight Loss And More

Hearts broke in Hollywood this week as longtime young lovers Miley Cyrus and Liam Hemsworth announced their split.

After months of speculation, Cyrus and Hemsworth's reps confirmed that the couple had called off their 16-month engagement. The pair met in 2009 on the set of "The Last Song" and got engaged in May 2012.

But it appears Cyrus, 20, and Hemsworth, 23, may have been broken up for longer than we thought -- a day after the split was revealed, Liam was seen kissing his reported new girlfriend, 23-year-old model-actress Eiza Gonzalez. The duo was first spotted cozying up in Las Vegas over the weekend at XS nightclub.

Cyrus has yet to say anything regarding the breakup, but she's sparked rumors of her own: Last we heard, she was getting cozy with her producer, Mike WiLL Made It.

In other news, Christina Aguilera looked incredible on "The Tonight Show" Sept. 18, displaying her weight loss in a little black dress. The "Voice" coach admitted she "feels sexier than ever" while discussing her Maxim shoot. Looking good, Xtina!

Gwyneth Paltrow also got candid about her sexuality on "Chelsea Lately" this week. The mom-of-two and wife of Coldplay frontman Chris Martin joked about her "sex addiction" with Chelsea Handler, saying, "Well, basically I was a really normal person, and then I started hanging out with you all the time.” Oops!

Also this week, Kim Kardashian posted another selfie, Zac Efron reportedly completed a stay in rehab, Jennifer Garner confronted the paparazzi and Jennifer Aniston confirmed, once again, that she is NOT pregnant.
