Britney Spears, 39, is thankful one of her fellow pop stars — Lady Gaga — is showing support after her 13-year-long conservatorship came to an end. The “Stronger” singer sent some kind words to Gaga, 35, on Monday, posting a photo to her Instagram of the “Poker Face” singer and a subsequent video of her at the House of Gucci Milan premiere on Nov. 13 in which she voices her support of Britney and says she “will forever be an inspiration to women.”
