The 21 and now legal "Come and Get It" singer has been seen getting her Jack in the Box on quite often. The starlet, who has been seen in Jack in the Box drive-thru lines ordering Western Bacon Cheeseburgers and tacos, was all smiles and laughs when blowing out her 21st birthday candles on her Jack in the Box taco cake, with more than a dozen tacos holding up a "21" candle. Gomez’s Instagram taco tweet received 255,000 likes on Instagram, 19, 137 retweets, and 12, 626 favorites, with responses like "Save me one!" and "The best cake ever!" The Jack in the Box official Twitter account even tweeted the actress with a Vine thanking her for her taco love, along with an accompanying retweet of her cake with the caption: "When you’re ready come eat Tacos. Nananana. RT My cake was... Jack n the box tacos... Yes!"
