Budding actress Ava Sambora gave Heather Locklear a run for her money in the beautiful blonde stakes at the LA premiere of This Is 40 on Wednesday.

There's no tension between them though - the pair are mother and daughter.

The 14-year-old, whose father is Bon Jovi guitarist Richie Sambora, makes her acting debut in the Judd Apatow film.

The comedy, which also stars Megan Fox and Paul Rudd follows a couple's experiences of getting older.

In 2010 Ava appeared on the catwalk to promote her father's clothing line White Trash Beautiful.
