London, Feb 24 : Lily Allen and Lindsay Lohan have proved that they are Best Friends Forever after they were spotted showing off matching tattoos.

The British singer and American actress were seen hanging around in Los Angeles displaying their new `Shhh' tattoo, reports the Sun.

But, it seems that, the Mean Girls star's father is not so happy with the pair's budding friendship, if her pal is to be believed.

The friend claims Michael has been making bizarre posts about Lily, as well as Lohan''s girlfriend Samantha Ronson on Twitter. (ANI)
