Well, I can tell you one. Back then, Miley Cyrus (a.k.a., Hannah Montana) was shooting new episodes of her Disney show and she became increasingly popular in 2007-2008. Her rising success is what gave her the chance to be on popular shows such as the Ellen Show, Good Morning America and a lot more. Back then Miley was 14 or 15, and was just starting her second year of shooting her show, Hannah Montana. It may have been her third season but I'm not sure because she only shot about 5 seasons before she left the Disney Channel. Hope this helps.

Since celebrities are people, it's appropriate to use a collective noun used for people that applies to the situation; for example a crowd of celebrities, a team of celebrities, a collection of celebrities. You can also be creative, for example a glittering of celebrities, a swarm of celebrities, a celebration of celebrities, a plague of celebrities, etc.
