Justin Timberlake

For Mother's Day today, several of our favorite stars -- including Demi Lovato, Channing Tatum, Rihanna, Miley Cyrus, Justin Bieber, Britney Spears, Lucy Hale, Kim Kardashian -- tweeted Happy Mother's Day wishes to their moms and moms around the world, and also shared some private photos with their moms. Here are some of our favorites:

Our minds have just exploded here at PopCrush, because both Justin Timberlake and Lance Bass have dropped two bombshell revelations about their time in 'N SYNC. Seriously, these stories are huge!

A new Michael Jackson song, titled 'Love Never Felt So Good,' made its debut last night (May 1) and the King of Pop got a little help his modern contemporaries. Usher danced along to the song as a snippet was played at the iHeartRadio Music Awards. Meanwhile, the track was officially released to iTunes late last night, with Justin Timberlake lending his voice to help modernize the archived MJ song

Thanks to the powers of Instagram, Justin Timberlake just shocked the world with a huge revelation -- he's on Michael Jackson's posthumous album, 'Xscape.' In the photo, JT revealed the single art for 'Love Never Felt So Good,' the track he (apparently!) sings on.

For those of you who might have missed Justin Timberlake’s 20/20 Experience World Tour when it came near you, there’s no need to panic -- JT’s got you covered in 2014. The singer-songwriter is hitting North American roads once again in November.

Justin Timberlake is just one big hopeless romantic! During his performance of 'Mirrors' last night at his tour stop in Sheffield, U.K., one fan was so moved that he popped the question to his girlfriend right there in front of the singer. JT caught the romantic act and announced the couple's engagement onstage, much to their surprise and delight.

SexyBack is not bound by time or space or periods in history. Justin Timberlake has a look-alike from the 1870s, and the resemblance is uncanny. While the singer's doppelgänger isn't nearly as snazzy of a dresser as JT himself, their facial features and hair/beard textures are really similar. The look-alike also has a bit of a serious vibe to him; check out the furrowed brow and his intense stare.

Stop it. Stop it right now, '90s-era celebrities and boy bands -- our hearts can't take any more nostalgia! (Just kidding, they totally can and bring it on.)

Justin Timberlake's video for 'Not a Bad Thing' is based on the true story of a guy who proposed to his girlfriend on a Long Island Rail Road train on the way to NYC on Jan. 12, using JT's song to do it! The singer --and hopeless romantic-- wants to get in touch with the couple and used the video as the medium.

We knew we would be getting to know Lindsay Lohan better through her new OWN documentary series, 'Lindsay' -- but we never saw this coming! InTouch has reportedly obtained Lohan's "Hollywood hookup" list -- aka a handwritten list of all of Lohan's famous conquests -- and it contains some A-list stars.
