Social Media Roundup: J Balvin, Kate del Castillo, Eva Longoria & More Get Together With Famous Friends

Besides selfies and photo shoots, celebrities sometimes share images of their friends on Instagram. These friends can sometimes, however, be other famous stars we all know and love. Check out which celebs took time to hang out together this past week.

Reggaeton artist, J Balvin shared a snapshot on Instagram of himself, fellow Colombian singer Juanes and his son Dante, and pop star Austin Mahone all hanging out backstage during the 2015 Kids Choice Awards Colombia.

The rapper captioned the photo with "La Familia," a phrase he is credited for starting when he used it as the name of his 2013 album and current tour.

Mahone, who recently split from Balvin's tour mate Becky G, also shared the photo, as did Juanes. Balvin also later posted a photo of himself and Juanes hanging out together in matching outfits.

Actress Eva Longoria and "Dueños del paraíso" star Kate del Castillo got together for work and for charity. The two actresses have been working together on the set of the new NBC series "Hot & Bothered," starring Longoria as a telenovela actress who can't speak Spanish, reported People.

Castillo and actor Carlos Ponce will both be making guest appearances in the television series, which also stars Cuban singer and actor Jencarlos Canela and "Prison Break" star Amaury Nolasco.

The cast took photos together on set, which Longoria, Castillo, Nolasco and Ponce all shared. They also got together to promote the "I Love Venezuela Foundation" in another image.

Jessica Alba also shared a photo with one of her famous friends, actress Reese Witherspoon, on Instagram.

Alba, who owns the lifestyle product brand The Honest Company, may have been giving Witherspoon, who recently launched her own southern living lifestyle blog and shopping site, Draper James, some pointers during a girls night out.

The photo also included model Kelly Sawyer and fashion writer Derek Blasberg.
