They keep their relationship extremely private and rarely speak about the other.

But Kristen Stewart and Robert Pattinson put on an affectionate display in front of the cameras today.

The chemistry between the couple was on show for all to see as they took part in the hand and foot prints ceremony at Graumans Theatre earlier yesterday.

Hands on: Kristen Stewart and Robert Pattinson were seen flirting at the Hand and Foot Print ceremony in LA earlier today

The pair were joined by their Twilight co-star Taylor Lautner, but the couple only had eyes for each other.

Kristen, 21, was seen placing her hand on her boyfriend’s thigh, an intimate gesture rarely seen from the publicity-shy couple.

The actress was dressed in a super short nude dress with black piping and beaded detail taken from the Marios Schwab Spring/Summer 2012 collection.

While the frock showed off her trim legs it boasted a modest high neckline, suitable for the event.

Gone was the cast Kristen had been sporting on her right hand as she jetted into LA on Wednesday.

Robert, 25, had dressed up for the occasion too and looked dapper in a grey suit which he teamed with a white shirt leaving the top button undone.

The British actor couldn’t keep his eyes of his gorgeous girlfriend and the pair were see joking together.

The couple were also seen flirting after they had pressed their hands into the cement and the actress pushed her messy hands up towards her boyfriend’s face with a cheeky grin spread across her face.

Kristen couldn't stop smiling and she gushed to the crowd: 'This is so crazy for us. I've been so enamored by this business, Hollywood.'

She added: 'I think this is the coolest thing I've done in my life. I've grown up thinking that. I just love this business. This is insane that I'm doing this.'

While the loved up couple, who have recently spent time together in London, put an amorous display, Taylor smiled for fans.

The actor was dressed in a pair of dark jeans and a black shirt, taking a more casual approach to the ceremony than his co-stars.

The trio return to screens later this month in the highly-anticipated latest instalment in the Twilight Saga.

The film's director, Bill Condon, recently told Celebuzz why the film's much anticipated sex scene didn't feel like, well, a Twilight series sort of scene.

Sharing a joke: The couple stole many glances and shared jokes together throughout the day

'There are MPAA guidelines on thrusting intercourse,' Condon explained of the original scene shot for the PG-13 rated film. [Kristen] got very into it.'

The film is meant for teens, which is why the director was overly cautious as to how he filmed it.

'[The scene] was so much more about romance than it was about hot-and-heavy action,' he told MTV.com, adding that taking out the bit that made it R-rated was a 'very simple adjustment to make'.

Kristen and Robert will appear in the first sex scene of the series - due for release on November 18.

And to add fuel to the hype, the actress has admitted that the first time they filmed it, things got so heated that the scene had to be completely re-cut.
