90210's Jessica Lowndes puts on a cheeky display in criss-cross thong bikini as she posts a string of sizzling swimwear pictures

With a postcode like 90210, actress Jessica Lowndes was barely out of her bikini in the noughties TV series.

But it seems like nothing's changed for the raven-haired beauty who has been sharing sun-soaked snaps in yet another gorgeous two piece.

Jessica, 26, shot a glimpse at her summer-ready stomach and pert posterior as she posed in a glamorous fashion for her latest social media posts.

Sensational display: Jessica Lowndes reveals her summer-ready frame in a black criss-cross bikini in a series of snaps for Instagram

The stunner was snapped on a yellow beach towel, resting against a wall with her tresses swept over one shoulder.

Her plunging bikini top offered just enough support as it cut low to reveal her golden decolletage and she matched a pair of criss-cross bottoms to the swimwear set to show off her sensational frame from behind.

Jessica is most famous for playing Adrianna Tate-Duncan in E4 series 90210 but also dated ex Scottish rugby player Thom Evans, a former flame of Brit beauty Kelly Brook, until late 2013.

Speaking about how she maintains her shape to Now magazine recently, the beauty said that weights and yoga are behind her toned appearance.

She said: 'I usually train with weights three times a week with a trainer. On other days I supplement that with other exercises - yoga, spinning, running, I make sure I take my diet seriously and remain consistent. That's the key.

'I don't really ever dread exercise. I may not like certain things on certain days. But for the most part I love exercising. It's just my therapy.' 

Glam: Jessica shared a selection of pictures of herself as she relaxed on a beach in Los Angeles recently too

And the actress certainly isn't shy about showing off her gym-honed shape, regularly filling up her Instagram feed with bikini-clad pictures on the beach. 

Jessica provided yet another luxurious-looking insight into her world on last Thursday with a shot of her looking out into the sunset, her peachy derriere in frame once again.

Jessica's last major role was opposite Jason Patric and Bruce Willis in The Prince, as a bartender who must help a retired hitman get his daughter back. 

This year she'll be seen in more of a grim role in an Abbatoir, which follows an investigative reporter's efforts to solve the mystery of a haunted house constructed from rooms of the deceased.
