The Comeback Kid

Young American singer Sebastien de la Cruz is back again. After performing the anthem at game 3 of the NBA finals between the Miami Heat and the San Antonio Spurs, critics lashed out on Twitter against his heritage. But Cruz didn't let the noise drown out an encore. Introduced by San Antonio Mayor Julian Castro, Cruz returned once more to perform the National Anthem before game 4, drawing applause throughout his rendition.

The Return of the Phelps

An image is blazing a trail across the internet tonight. Michael Phelps posted a photo on his Instagram account that showed him on the starting block with the quote "One on one training session with @coach_bowman." Bowman was the man who helped him win 18 Olympic gold medals. Tonight, the photos fueled speculation that the retired Phelps will be back for the Rio Olympics in 2016. So far, Phelps is letting the picture do the talking.

The Calm Before the Vows

A picture shared on Facebook and online by so many has captured the spirit of marriage. A bride and groom clasped their hands together moments before walking down the aisle in a quiet moment of prayer. The groom averted his eyes, reaching around a wall so that he would not see the bride in her dress. The groom said it was important - in the midst of their wedding day frenzy - to give thanks before taking those precious vows.
