Simon Cowell joins Instagram

Media mogul Simon Cowell has finally joined photo-sharing website Instagram.

Cowell, 56, went on a posting spree, uploading several snaps from the glitzy Brit Awards.

The first photo was of himself and his girlfriend Lauren Silverman, striding into the O2 Arena hand-in-hand.

American beauty Lauren wore an elegant dress that featured a high collar and embellished detailing, while Cowell looked dapper in a tuxedo.

The couple featured in another snap taken at their champagne-filled table, this time posing with Louis Tomlinson. The photo did little to dispel rumours that the One Directioner may be joining "The X Factor" panel as a judge.
