Kelly Osbourne has apologized to Lady Gaga for the birthday cake blunder, saying that she acted like a child.
The 28-year-old TV host took to twitter and asked the 27-year-old singer to call her and end their feud like adults, as she doesn't want to fight anymore, the New York Daily News reported.
The E! host had rejected Gaga's "peace offering" by posting a photo of the cake sent by her with the caption 'Eatmys**t'.
